    In recent years, to reduce manufacturing costs and decrease the rare-earth supply/demand imbalance in the Nd–Fe–B magnet market, (Nd,Ce)–Fe–B magnets, in which Nd is replaced by Ce, have gained significant attention. In this study, we investigated the magnetic properties and microstructures of anisotropic (Nd,Ce)–Fe–B powders treated by hydrogenation–disproportionation–desorption–recombination (HDDR). The demagnetization curve of Nd12.5Febal.B6.5Nb0.2 after the grain boundary diffusion (GBD) process exhibited high squareness, whereas that of (Nd0.5Ce0.5)12.5Febal.B6.5Nb0.2 exhibited low squareness with a knick. Generally, the low squareness of the demagnetization curve is caused by the presence of different HcJ regions in the material. The XRD, SEM, and STEM-EDX analyses revealed the generation of different HcJ regions owing to two factors. The first was the presence of a ferromagnetic RFe2 (R = Ce and Nd) phase surrounding the R2Fe14B phase, which was observed in the starting material after HDDR and GBD. Consequently, this region showed a lower HcJ than other typical regions in which the R2Fe14B grains were surrounded by an R-rich phase. The second was the inhomogeneous distribution of Ce and Nd in each R2Fe14B grain. This inhomogeneity stemmed from differences in the equilibrium conditions of the HDDR reaction between Nd2Fe14B and Ce2Fe14B, leading to variations in the magnetocrystalline anisotropy and HcJ in the R2Fe14B grains.

    Abstract In advanced applications such as aerospace and space exploration, materials must balance lightness, functionality and extreme thermal fluctuation resistance1,2. Shape-memory alloys show promise with strength, toughness and substantial strain recovery due to superelasticity, but maintaining low mass and effective operation at cryogenic temperatures is challenging3–6. We hereby introduce a new shape-memory alloy that adheres to these stringent criteria. Predominantly composed of Ti and Al with a chemical composition of Ti75.25Al20Cr4.75, this alloy is characterized by a low density (4.36 × 103 kg m 3) and a high specific strength (185 × 103 Pa m3 per kg) at room temperature, while showing excellent superelasticity. The superelasticity, owing to a reversible stress-induced phase transformation from an ordered body-centred cubic parent phase to an ordered orthorhombic martensite, allows for a recoverable strain exceeding 7%. This functionality persists across a broad range of temperatures, from deep cryogenic 4.2 K to above room temperature, arising from an unconventional temperature dependence of transformation stresses. Below a certain threshold during cooling, the critical transformation stress inversely correlates with temperature. We interpret this behaviour from the perspective of a temperature-dependent anomalous lattice instability of the parent phase. This alloy holds potential in everyday appliances requiring flexible strain accommodation, as well as components designed for extreme environmental conditions such as deep space and liquefied gases.

    The full Heusler alloys Ni2MnZ (Z = In, Sn, Sb) exhibit ferromagnetic properties with a Curie temperature (TC) above room temperature. The magnetic properties of Ni2MnZ (Z = In, Sn, Sb) were studied through a combination of experiments and band calculations under ambient and elevated pressures. The main results of this study open up further prospects for controlling the magnetic properties of the multifunctional Heusler alloys Ni2Mn1+xZ1−x (Z = In, Sn, Sb) and their practical application.

    Objective: Evaluate the efficacy of a new orthotic-made super-elastic alloy brace to correct hallux valgus (HV) deformity.Methods: Five female patients diagnosed with HV deformity wore the newly developed orthotic daily for six weeks. The orthotic wasdeveloped using a super-elastic alloy brace to correct great toe lateral deviation, first metatarsal medial deviation, and fixation belts.The correction was evaluated by measuring the load at which the big toe begins to move and the distance moved by 15 gf force whenpulled from the side. Results: The orthotic was worn by all patients without causing any sleep disruptions. In the initial state, a strong force was required to move the big toe, but after two weeks, it was significantly improved to be mobile in all patients. Conclusion: The developed HV orthotic has a high wearability without causing pain or discomfort. Long-term use can provide a consistent and continuous correction force to the big toe, resulting in the successful release of the big toe metatarsophalangeal joint contracture within two weeks. Level of Evidence: Level 4.

    The demand for biomaterials has been increasing along with the increase in the population of elderly people worldwide. The mechanical properties and high wear resistance of metallic biomaterials make them well-suited for use as substitutes or as support for damaged hard tissues. However, unless these biomaterials also have a low Young's modulus similar to that of human bones, bone atrophy inevitably occurs. Because a low Young's modulus is typically associated with poor wear resistance, it is difficult to realize a low Young's modulus and high wear resistance simultaneously. Also, the superelastic property of shape-memory alloys makes them suitable for biomedical applications, like vascular stents and guide wires. However, due to the low recoverable strain of conventional biocompatible shape-memory alloys, the demand for a new alloy system is high. The novel body-centered-cubic cobalt-chromium-based alloys in this work provide a solution to both of these problems. The Young's modulus of <001>-oriented single-crystal cobalt-chromium-based alloys is 10-30 GPa, which is similar to that of human bone, and they also demonstrate high wear and corrosion resistance. They also exhibit superelasticity with a huge recoverable strain up to 17.0%. For these reasons, the novel cobalt-chromium-based alloys can be promising candidates for biomedical applications.

    This study investigates the crystal structure, martensitic transformation behavior, magnetic properties, and magnetic-field-induced reverse martensitic transformation of Co64V15(Si21–xAlx) alloys. It was found that by increasing the Al composition, the microstructure changes from the martensite phase to the parent phase. The crystal structures of the martensite and parent phases were determined as D022 and L21, respectively. Thermoanalysis and thermomagnetization measurements were used to determine the martensitic transformation and Curie temperatures. Both the ferromagnetic state of the parent phase and that of the martensite phase were observed. With the increasing Al contents, the martensitic transformation temperatures decrease, whereas the Curie temperatures of both the martensite and parent phases increase. The spontaneous magnetization and its composition dependence were also determined. The magnetic-field-induced reverse martensitic transformation of a Co64V15Si7Al14 alloy under pulsed high magnetic fields was observed. Moreover, using the results of the DSC measurements and the pulsed high magnetization measurements, the temperature dependence of the transformation entropy change of the Co-V-Si-Al alloys was estimated.

    The magnetization, electric resistivity, and magnetoresistance properties of Pd 2 Mn 1 . 4 Sn 0 . 6 Heusler alloys were investigated. The Curie temperature of the parent phase, martensitic transformation temperatures, and magnetic field dependence of the martensitic transformation temperatures were determined. The magnetoresistance was investigated from 10 to 290 K, revealing both intrinsic and extrinsic magnetoresistance properties for this alloy. A maximum of about - 3 . 5 % of intrinsic magnetoresistance under 90 kOe and of about - 30 % of extrinsic magnetoresistance under 180 kOe were obtained. Moreover, the thermal transformation arrest phenomenon was confirmed in the Pd 2 Mn 1 . 4 Sn 0 . 6 alloy, and an abnormal heating-induced martensitic transformation (HIMT) behavior was observed.

    <p>An interface is a structural imperfection that significantly affects magnetic and electric properties in crystalline solids. Studies of the interface magnetism are vitally important for technologies related with permanent magnets, magnetic recording, magnetoelectronics, etc. However, it remains yet challenging to reveal the magnetism in natural interfaces, such as antiphase boundaries (APBs) in ordered alloys, because of the complex shape and the extremely small thickness. This paper reports on the electron holography study that determined magnetic flux density from narrow APBs produced in an ordered alloy, Fe70Al30.</p>

    The microstructure and superplastic behavior at 450℃ and 500℃ were investigated using optical microscopy and a tensile test in Cu-Al-Mn-Ni shape memory alloy. It was found that a fine α(fcc) + β(bcc) two-phase structure with grain size of 3μm in diameter can be obtained by annealing at 600℃. The flow stress of the Cu-Al-Mn-Ni alloy is dependent on both the strain rate and the test temperature where the strain rate sensitivity is over 0.3 which exhibits superplasticity with the elongation of over several hundred percents. For the test temperature at 500℃ and the strain rate of 5×10^<-4> sec^<-1>, the maximal elongation of 1150% was obtained.

    More details Close

    Martensitic transformation and superelasticity in Pd-In-Fe alloys were investigated. Pd-In-Fe alloys show martensitic transformation from a Heusler-type L2_1 ordered bcc phase to a 2M-type DO_<22> structure. It was confirmed from compressive test and three-point bending test that an almost perfect superelastic effect accompanying the stress-induced martensitic transformation can be obtained. Since high corrosion resistance and specific gravity are expected in these Pd-based shape memory alloys (SMAs), the present alloys are potentially applicable for medical devices.

    Cu-based shape memory alloys (SMAs) of the Cu-Zn- and Cu-Al-based systems are commercially attractive for the manufacture of practical applications based on the shape memory effect (SME) and superelasticity (SE) because of their low cost compared with Ti-Ni (Nitinol) SMAs. However, conventional polycrystalline Cu-based SMAs are too brittle to be sufficiently cold-worked, which restricts the attainable SE strain to only about 2%. During the last decade, we have developed ductile Cu-Al-Mn-based SMAs with excellent shape memory properties. However, the Cu-Al-Mn-based SMAs show low fatigue strength. In the present study, effect of ageing treatment on the mechanical properties for the Cu-Al-Mn-based SMA was investigated by tensile testing. It was seen that the yield stress and the tensile strength of the Cu-Al-Mn-based SMA drastically increase with the ageing without the associated loss in the superelasticity.

    Nitinol shape memory alloys (SMAs) are attracting considerable attention as core materials for medical guidewires because of their excellent flexibility and shape retention. However, since Nitinol guidewires possess low rigidity, the pushability and torquability of the guidewires are insufficient. On the other hand, although stainless steel guidewires have high pushability, plastic deformation easily occurs. We have developed a new class of superelastic guidewires with functionally graded properties from the tip to the end by using new SMA core materials such as Cu-Al-Mn-based or Ti-Mo-Sn SMAs. The tip portion of the guidewire shows excellent superelasticity (SE), while the body portion possesses high rigidity. These functionally graded characteristics can be realized by microstructural control. These guidewires show excellent pushability and torquability and are considerably easier to handle than conventional guidewires. Moreover, a metallic catheter using a Ni-free Ti-based SMA with high biocompatibility is introduced.

    We have investigated that the structural and magnetic properties of Co2CrGa full-Heusler alloy films and researched the tunnel magnetoresistance (TMR) in magnetic tunnel junctions (MTJs) using a Co2CrGa electrode on a MgO(100) substrate. Co2CrGa films were fabricated with substrate heating (RT ≤ Ts ≤ 500°C) or post-annealing (RT ≤ Ta ≤ 500°C) after the deposition using an ultrahigh vacuum dc magnetron sputtering system. L21-ordered Co2CrGa thin films were obtained at Ts ≥ 300°C or Ta ≥ 200°C. The maximum magnetic moment per formula unit measured at 5 K were 2.8 μB and 2.6 μB for TS and Ta = 400°C, respectively, which are over 85% of the theoretical value. The maximum TMR of 18% at RT and 42% at 5 K are obtained for the MTJ using the L21-structured Co2CrGa film as a bottom electrode. It is expected that the TMR can be enhanced by optimizing the interface of Co2CrGa/AlOx.

    More details Close

    Microstructure of Cu-Fe base alloy powders produced by conventional gas atomization was investigated and an egg-type core structure consisting of two or triple layers was obtained in the alloy systems which have a stable miscibility gap in the liquid phase. It was found that the minor liquid phase, which is dependent on the chemical composition of the alloy, always forms the core in a powder, assembling to the center of the powder. The origin of the formation of this core microstructure can be explained by Marangoni motion on the basis of the temperature dependence of the interfacial energy between the Fe- and Cu-rich liquid phases.<br> In principle, since the egg-type powder may be formed not only in alloy systems, but also in immiscible ceramics and polymer systems, it is expected for this new type of powder with the core structure to be utilized for various technical applications, such as electrical, chemical, magnetic parts, etc.

    According to some theoretical studies, auxetic property, i.e., negative Poisson’s ratio, is predicted in many bcc-based Intermetallic Compounds (IMCs). In the present study, some CuAlMn single crystals obtained by cyclic heat treatment from LD<110> texture samples were investigated to prove the peculiar property. By application of tensile stress to LD[110], the negative Poisson’s ratio was confirmed in [1-10] direction, which was consistent with the theoretical results predicted with the moduli experimentally obtained. Furthermore, in [001] direction, a large Poisson’s ratio over 1.0 was detected. These properties were also obtained in the {001}<110> textured polycrystalline sample fabricated by cold rolling and annealing. This means that the properties are available to functional devices such as mechanical diode.

    For the dilute solid solution alloys A-X (X: Au, Re and W), the direct observation of jumping process of the solute atoms was carried out by STEM-HAADF observation in different several scanning beam conditions. It was confirmed that the frequencies of atomic jump for these alloy systems are higher in the order of Au>Re>W and depend on the scanning rate and the beam intensity. This means that the atomic jump is excited by incident electron beam, not due to the regular diffusion. By precise analysis for the jumping behavior in the Re-doped alloy, it was clarified that the jump is isotropic in direction of every nearest neighbor site. The evaluation of solubility limit of solute element Au was performed by counting all the atomic positions in a fixed flame of the HAADF-STEM image. The obtained result was consistent with that estimated by electric resistant measurement.

    Abnormal grain growth phenomenon induced by cyclic heat treatment through α→α+β→β phase transformations was investigated in Cu-Al-Mn and Fe-Mn-Al-Ni alloys. It was found that the subgrain structure forms associated with precipitation of the second phase and that it exists after solution treatment. Annealing at higher temperatures resulted in abnormal grain growth, and the subgrain free zone was observed after migration of the high-angle boundary. The abnormal grain growth can be explained by considering the sub-boundary energy as a driving pressure.

    Ni-based superalloys strengthened by Ni3Al gamma-prime phase with the L12 structure show good high-temperature strength. It has been also found that gamma-prime phase exists in the Ir-Al-W system. This study was intended to develop Ni-Ir-Al-W alloys having excellent high-temperature strength. We determined the phase diagrams of the Ni-Ir-Al-W systems. It was found that the gamma-prime phase can be stabilized by addition of Ir and W to Ni-Al alloys and that the melting temperature also increases. The Ni-Ir-Al-W alloys show higher strength at higher temperatures compared with that in Ni-based superalloys.

    Recently, in the CoCrGaSi Hesler alloy system, an anomalous martensitic transformation (AMT), where the L10 martensite phase transforms again to L21 parent phase on cooling, have been found. Moreover, cooling-induced shape memory effect has first been reported by using the thermoelastic AMT. In this study, for the CoCrGaSi Hesler alloys, basic physical and superelastic properties were examined in order to clarify the origin of the abnormal phenomenon. Through this project, it has been suggested that its origin may be due to magnetic transformations in both the parent and martensite phases.

    Effect of liquid particles on grain growth in multi-phase structure was investigated. The following results were obtained. (1) The grain growth of monotectic-type Fe-Bi, Zn-Bi and Al-Bi alloys was retarted by the dispersion of liquid particles with the formation of precipitation-free zones (PFZs) and large Bi particles located on the grain boundaries. (2) The grain growth characteristics of the liquid Bi particles dispersion structure of the two-phase (ferrite ((α) + liquid or austenite ((γ) +liquid) and the triple-phase (α+γ+liquid) in Fe-Mn-Al-Bi alloys show that when the matrix in the two- or triple-phase structures was the α phase, the fine Bi particles were dispersed within the α grain together with the formation of PFZs, while the matrix in the two- or triple-phase structures was the γ phase, most of the Bi particles were basically located on the grain boundaries.

    It has been accepted that it is difficult to control the coefficient of thermal expansion (CTE) because it inversely proportional to the melting point of materials. This study was aimed to develop a new method of controlling the CTE using phase transformation. It is known that plastically deformed alloys undergoing thermoelastic martensitic transformation can exhibit two-way shape memory effect, which is a reversible and spontaneous shape change during heating and cooling. The effect of the pre-deformation on the reversible shape change was quantitatively investigated in this study. It was found that the transformation hysteresis increases by cold-rolling and CTE【approximately equal】0 is obtained in Cu-Zn-Al alloy cold-rolled to 9% reduction. Although the one directional rolling causes anisotropy in CTE, two-dimensional low thermal expansion (LTE) can be obtained by a cross-rolling method. Moreover, the cold-workability is drastically improved in α+β two-phase alloys, which means that Cu-Zn-Al Invar alloys possessing high electrical conductivity are promising for practical applications. The grain size is one of the important factors to control the thermal expansion property. It was found that higher reduction is required to obtain LTE in a large grain specimen, which was thermodynamically analyzed using the Clausius-Clapeyron relationship, leading to the establishment of a method of controlling the CTE of alloys. Single crystal experiments also clarified the mechanism of the LTE obtained in these new Invar alloys. The stability of Cu-Zn-Al Invar alloys was investigated. 500 thermal cycles between-190℃ and 90℃ hardly changed the thermal expansion property, and good thermal stability up to 80℃ was confirmed. Based on the results in this study, the Cu-based Invar alloys are being examined for applications particularly to a machine part in printers. It should be noted that several interesting results related to this study, including high damping capacity, improvement of fatigue properties and superplasticity, was obtained in the Cu-Zn-Al and Cu-Al-Mn alloys.

    申請者は最近、1000℃以上の高いキュリー温度を有し400℃程度にfcc/hcp変態を持つCo系合金に着目し、そのマルテンサイト変態挙動を調査したところ、簡易的な曲げ試験で2%の表面歪に対し、約80%の形状回復が得られることを見出した、この合金のキュリー温度は約800℃、マルテンサイト逆変態温度は約200℃であり、形状回復もこの逆変態に起因して高温で生じていることを確認した。そこで、本研究ではCo-Alを始めとしたCo-X(X : Ni, Fe, Ga, Si, Ge)系におけるfcc/hcpマルテンサイト変態について、合金元素や熱処理の効果を詳細に研究し、新規高温形状記憶合金としての可能性を明確にする。平成17年度に得られた結果は以下の通り。 1.優れた形状記憶効果を示したCo-Al合金について、形状記憶特性や磁気特性に及ぼす時効熱処理の影響を調査した。その結果、800℃における時効処理により優れた形状記憶特性が得られた。 2.優れた形状記憶特性が得られた時効材の電子顕微鏡組織観察を行い、マルテンサイト組織と時効組織との関係を調査した。その結果、800℃における時効処理によりマトリックス以外に規則B2相が析出している事が判明した。優れた形状記憶特性が得られた理由は、析出物による強化が一因と考えられる。 3.Co-Al合金はマルテンサイト変態温度が200℃程度と低い。従って、より高い変態温度が期待できるCo-Si合金を調査した。その結果、変態温度は600℃以上に出来るものの、形状記憶特性は40%程度とCo-Al系に比しても十分なものとはならないことが判明した。 4.上記Co系形状記憶効果の発現機構については、その挙動が複雑なために明確にする事はできなかった。しかし、Fe-Mn-Si系とは異なり、良好な形状記憶特性を得る条件として変形加工前にマルテンサイト相が既に存在している事が重要である事が判明した。

    現在までに数多くの制振材料が開発されてきたが、実用に十分な制振特性とは言えず、実用材としてさほど普及してしていないのが実情である。近年NiMnGa系やFePd系などの強磁性形状記憶合金が盛んに研究されているが、申請者らもCoNiAl系で加工性に富む形状記憶合金を開発した。この合金の磁区構造を観察したところ熱弾性型マルテンサイト相に特有のマイクロ双晶と磁壁が共存する組織であることが判明した。この様なタイプの合金は従来まったく存在しないので、両組織因子の存在が制振特性にどのような影響を及ぼすか非常に興味が持たれる。そこで、本研究は、CoNiAl系強磁性形状記憶合金、および昨年初頭に我々が新たに開発したNiFeGa系強磁性形状記憶合金合金についてその制振特性への磁気変態温度、マルテンサイト温度、結晶粒径等の組織学的因子の影響を明らかにし、磁壁と双晶界面の相互作用について知見を得ることを目的としている。 本年度得られた成果は、以下の通りである。 1.NiFeGa系強磁性形状記憶合金合金について計算状態図の手法を利用して、(1)常磁性母相〜強磁性母相〜強磁性マルテンサイト(M)相、(2)常磁性母相〜強磁性M相、(3)常磁性母相〜常磁性M相〜強磁性M相の3種類の変態モードを得るための合金設計を行った。 2.NiFeGa系強磁性形状記憶合金合金についてローレンツ顕微鏡および電子線ホログラフィにより、それら(1)の変態モードにより得られる磁区・マルテンサイト双晶組織を観察し、組織的な特徴を明確にした。 3.NiFeGa系単結晶を作成し、磁壁移動または双晶移動がそれぞれ単体として作用する場合の制振特性を評価した。その結果、単結晶の制振特性は他の制振材料と比して際立って優れていること、しかしながら0.1Hz〜10Hzの範囲では、強磁性相中に導入されている磁区の移動による制振効果はほとんど見られず、マルテンサイトの相晶移動や晶壁面移動による効果が支配的であることが判明した。 4.CoNiAl系多結晶合金を組織制御により高加工性とし、2相組織の体積分率の効果や、結晶粒径の効果を明確にした。

    The Pb-Sn alloy was widely used as micro-soldering materials in electronic packaging. However, The Sn base Pb-free solders to replace conventional Pb-Sn alloys have been designed and developed to meet the requirements arising from environmental and health issues concerning the toxicity of Pb. The interfacial reaction and microstructure between Cu substrate and Sn base Pb-free solders to the reliability of electronic packaging are very important. In the present project, the interfacial reaction and microstructure between Cu substrate and Sn base Pb-free solders were experimentally investigated. The main research results are as follows : (1) In order to obtain the information related to microstructure control and phase equilibria, the phase diagrams in the Cu-Sn-X system (X : Ag, Bi, In, Sb, Zn) were experimentally determined in some important alloy systems for which there has been little or no experimental data. The thermodynamic calculations for these systems were also carried out on the basis of CALPHAD method ( Calculation of Phase Diagrams). A good agreement between the calculated and experimental results is obtained. (2) Cu/Sn-X alloy (X : Ag, Sb, In, Bi, Pb) solid/liquid diffusion couples were prepared, and treated at 250, 250 and 300℃. The dissolution behavior and morphology of microstructure in molten Sn base solders were investigated with different times and temperatures. In particular, the reason for the uneven interface between h phase and liquid phase was explained due to the grooving effect. (3) On the basis of diffusion coefficients estimated by the present study and reported by previous works, the kinetic parameters describing the dissolution behavior between Cu and Sn-X solders were optimized. Using these parameters, the simulation of diffusion behavior was carried out, and calculated results are in good agreement with the experimental data.

    Shape memory (SM) material which possesses double functions of thermo-sensor and actuator is one of the typical smart materials. Although the SM devices yield larger power and displacement than the ferroelectric one, they have a very serious problem in which the response for input signal is too slow, because the thermal conductivity in the SM devices is a rate determining process. Recently, ferromagnetic Shape memory (FSM) alloys that can be operated by magnetic field have been developed in the Ni-Mn-Ga system. In the present study, new type of FSMAs, Co-Ni-Al alloys with B2 bcc ordered structure were investigated.. The details of results obtained by the present work are as follows: (1) Transformation temperatures: Martensitic transformation temperature (Ms) and Curie temperature (Tc) were determined by DSC and VSM measurement. Some alloys have Ms and To in relatively high temperatures region over room temperature. This result means that the Co-Ni-Al alloys can be a candidate of the promising FSMA. (2) Crystal structure: The parent and martensits phases have B2 and Ll_0 structures, respectively. The c/a ration of the Ll_0, phase is 0.81. (3) Shape memory and mechanical properties: Coexistence with γ phase improves the ductility of alloys and a perfect SM can be obtained by a training treatment. (4) Magnetic properties: Magnetic anisotropies of austenite and martensite phases were determined using single crystals, and magnetostriction of about 0.3% was detected. (5) FSM wire, FSM wire with 0.5 to 1.0mmf could be produced by conventional techniques of rolling and drawing. The obtained wire showed a pseudoelastic behavior.

    Cu基超弾性合金の電子および医療材料への展開を試みるため、超弾性特性の向上に有効と考えられる集合組織の形成を、特に線材、箔について、加工熱処理法による集合組織形成を検討した。また、変位センサー・圧力センサー等への応用を検討するため、超弾性効果に伴う合金の電気抵抗変化を調査し、次の知見を得た。 (1)焼鈍および冷間伸線後、再結晶させることにより、<110>繊維集合組織が形成されることが分かった。特に、α相分率(8184)16β相分率の比率を有するα+β2相組織にて冷間伸線を行う事により、その後の再結晶により強烈に<110>繊維集合組織が形成することが明らかとなった。一方、<110>繊維集合組織は、線材軸方向に<110>が揃うが、軸周りではランダムな配向になるため、回復歪み量は、完全ランダム方位を有する線材と変わらない。 (2)箔(〜30μm)についてもα+β2相組織にて冷間圧延を行う事により強烈な集合組織が形成され、特に{112}<110>集合組織が発達し、6〜7%程度の回復歪み量が得られる。 {112}<110>集合組織を有する板材あるいは箔では、現象論解析結果を用いた変態歪みの方位依存性解析より予測された圧延方向から45°回転させた方向において、9%程度の回復歪みが得られる事が明らかとなった。 (3)本Cu-Al-Mn基合金は、応力誘起マルテンサイト変態に伴い、電気抵抗は上昇する。その歪み感度(歪み量変化に対する電気抵抗変化率)は6.5と大きく、一般的に歪みゲージ等に使用されているCu-Ni合金の3倍以上である事が分かった。また、Ni-Ti形状記憶合金に比べて、歪み変化に対する電気抵抗変化の直線性が良く、6%程度の歪みを電気抵抗変化により可逆的に検出できる。また、歪み感度は、マルテンサイト変態温度に大きく依存する。

    It is well known that magnetic properties such as the Curie temperature and the mean magnetic moment of ordered compounds have different values from those of disordered solutions. In consequence, the stability of the ordered phase is depressed (enhanced) due to the interaction between the chemical and magnetic ordering caused by the decrease (increase) of magnetic properties. In this project, a new thermodynamic model taking into account the interaction effect was developed by the collaboration with prof. Bo Sundman in the Royal Institute of Technology, Sweden. Model calculations to describe the phase stability of the b.c.c. and f.c.c. structures were performed taking into account the magnetic and the chemical ordering reactions and also the mutual interaction between them. Thermodynamic assessments of the Fe-X (X=A1, Ni and Co) systems were also carried out using two- or four-sublattice s-CEF, including the interaction effect. These calculations lead to the following conclusions. (1) The incomprehensible A2+B2 phase separation and tricritical point in the Fe-Al system originate in the depressed chemical and magnetic ordering energies caused by the mutual interaction. (2) The stability of both γ'-FeNi_3 (L1_2) and γ"-FeNi (L1_0) compounds is strongly enhanced by the additional magnetic energy due to the chemical ordering. The calculated phase diagram suggests that the γ"-FeNi (L1_0) phase is stable. (3) In the Fe-Co system, the stability of the B2 ordering arises mostly from the enhanced magnetic energy due to the chemical ordering.

    The morphology of TiS and CrS in steels formed during solidification and the modification of this morphology by the addition of some alloying elements were investigated by means of optical and scanning electron microscopy. The thermodynamic analyses of phase equilibria of the Fe-Ti-S and Fe-Cr-S ternary systems were also carried out. The results obtained are as follows : 1. The morphologies of TiS can be classified into four types ; (i) fine-particle (ii) globular (iii) rod-like and (iv) plate-like sulfides, which depends on the Ti/S ratio and formation process. 2. The morphology of TiS in the Fe-0.5%Ti-0.3%S base alloy is the rod-like sulfide while additions of Mn and Zr change the morphology from rod-like to globular. The morphology of sulfide is discussed in terms of eutectic and monotectic-type phase diagrams in the Fe-sulfide quasi-binary system. 3. The solubility product of TiS in steel can be determined. log[Ti]γ[S]γ=7.74-17820/T, log[Ti]α, δ[S]α, δ=8.07-17171/T log[Ti]liq[S]liq=7.09-12447/T 4. The sulfide morphologies in the Fe-Cr-S ternary alloy are calssified into three types ; (i) cell wall (ii) fine particle and (iii) globular sulfides. Fine particle sulfide morphology is the result of the remelting or the eutectioid reaction attendant on the phase transformation of matrix from δ to γ. The morphology of sulfides changes from the cell wall and the fine particle type to the globular type with increasing Cr content. 5. Additions of Mn, Ti or Zr to Fe-Cr-S alloys lead to the formation of MnS, TiS or ZrS with the globular, the rod-like and the polyhedral morphologies respectively, which are due to the sulfide formation tendency of the additions and their effect on the nature of the phase diagram. 6. The solubility product of CrS in steel at 1%Cr level is determined. log[Cr]liq[S]liq=3.89-4500/T, log[Cr]δ[S]δ=3.35-6550/T log[Cr]γ[S]γ=3.43-7307/T, log[Cr]α[S]α=5.32-9068/T

    It is known that magnetic transition influences order-disorder transitions in the Fe-base alloys which show both the chemical ordering and magnetic transition. However, there are very few papers quantitatively discussing the interactions between those transitions. In the present project, the order-disorder and magnetic transition temperatures in some Fe-base and Co-base alloys has been examined and the interaction between them was evaluated by thermodynamic calculation using the CALPHAD-type and BWG analysis. In order to investigate this topic, the Fe-X (X : Al, Rh, Ga and Si) systems and the Co-Al-X (X : Ti, Ni) systems had been selected. The obtained results are as follows : (1) The magnetic and chemical ordering transition temperatures in the Fe-X (X : Al, Rh, Ga, Si) binary alloys were determined by VSM, differential scanning calorimetry (DSC) and electric resistance (ER) measurements. In the case of some alloys showing the 1st order transitions, the phase equilibrium between the ordered and disordered phases were examined by X-ray microanalysis (XMA) and transmission electron microscopy (TEM). It was clarified by these examinations that the interactions between the magnetic and chemical orderings exist there in the Fe-Al and Fe-Ga systems. (2) The magnetic and chemical ordering transition temperatures in the Co-Al-X (X : Ti, Ni) ternary alloys were also determined by VSM and DSC measurements. The phase equilibrium between the B2 and D03 phases were examined by TEM observation. (3) On the basis of those experimental results, the phase equilibria in the Fe-Rh and Fe-Al binary systems were analyzed using the CALPHAD-type thermodynamic calculation. In conclusions, it was proposed that since the magnetic properties are strongly affected by the degree of order in the ordered phase, and the new thermodynamic model which takes into account the interaction between the magnetic and chemical orderings should be used for precisely describing the phase stability of phases.

    Distinct features and functionalities of the object-oriented database system may be exploited in the construction of highly versatile phase diagram database services. To test and demonstrate this expectation, the following tasks were carried out : (1) an object-oriented database system program was developed from scratch and tuned for the phase diagram database services ; (2) Classes necessary for phase diagram databases were designed ; (3) Over a hundred phase diagrams were input to a database ; (4) A public phase diagram database service was carried out. During this research term, about 150 collection and improvements were made in the object-oriented database system, MOOD-SX, to achieve further versatility and higher performance. These include the transfer and display of image files and also the development of a user-interface Java applet that allows the database access from the popular web browsers. The MOOD-SX is enlisted in more than 5 public software archives such as SAL, Scientific Applications for Linux. In the class design, it was noted that the object-oriented class design was equivalent to the ontology in the field of knowledge engineering. Special care, therefore, was taken to make explicit and formal representations of concepts that appeared in the descriptions of equilibrium phase diagrams. For example : (1) a pseudo-binary phase diagram is specified with two terminal compositions but these compositions may be represented as well with substances with the compositions ; (2) a phase may be characterized with a crystal structure, a crystal structure being characterized with a structure type and composition ; and (3) phase as such is an entity distinct from substance. With the class set designed based on discussions as above, about 100 pieces of iron-base binary phase diagrams were input to a database together with about 300 phases and about 80 structure types that appear in the diagrams. The database was offered to public access. Upon this data input, several inconsistencies were found in the source information provided and well proofed in the form of printed tables. This demonstrates the effectiveness of the compilation of data in an object-oriented scheme.

    It is known that there are many kinds of transformations, such as A2/B2/D03/L21 order-disorder transitions, magnetic transition and phase separation in their ordered phases, in the β phase of the Cu-Al-Mn alloys. The purpose of this study is to develop some new types of Cu base alloys using these transformations. Actually high strength Cu alloys, shape memory (SM) alloys and giant magnetoresistance (GMR) thin films were examined in the present study. All the results obtained in this study are listed as follows : (1) High Strength Cu Alloys : In the Cu-13%Al-15%Mn-5%Ni alloys, very high level of tensile strength over 1000MPa were achieved due to aging at 300℃. According to TEM observation, it is seen that the microstructure of the as-aged specimens has a kind of bainate structure with very fine scale. Since such the high level of strength in the Cu base alloys has not been reported except the Cu-Be alloys, the present alloys have a potential for a new kind of high strength Cu base alloys. (2) Shape Memory Alloys Effects of alloying elements on the fabricability, Ms temperature and SM properties were examined. It was clarified that the precipitates decrease ductility, Si, Au and Co increase the Ms temperature and the SM properties are strongly influenced by grain size and texture. (3) Giant Magnetoresistance Thin Films GMR properties of Cu-Al-Mn alloys with wide range of compositions were examined. It was clarified that the Cu-25%Al-10%Mn alloy which has the volume fraction of Cu2MnAl:Cu3Al=3:7 shows the highest GMR ratio over 4%. Based on the above results, joint projects for practical applications with some companies are running.

    一般に、固液2相組織は、液相が固相の結晶粒界をフィルム状に覆うため、著しく脆いことが知られている。最近、少量の液相Biを分散させたAl-Bi合金は、脆化しないばかりか、超塑性を示すことが小池らにより報告された。本合金系で脆化しない理由は、現在のところ明らかではないが、Al-Bi系が典型的な偏晶型状態図を示し粒界と液相Biとの濡れ性が極めて悪く、液相Biが粒界上に粒子状に存在することが大きく関与していると考えられる。本研究では、このような特徴的な液相分散組織を有する、Al-Bi合金の粒界移動と結晶粒成長の挙動を明らかにすることを目的とする。 数vol%程度の液相Biを有する合金を高周波溶解した後、50%の冷間加工を行い、500℃で再結晶及び粒成長処理を行った。適当な時間の熱処理後、氷水中焼き入れし、Biの分散状態についてはSEMで、また結晶粒界組織については電界腐食後、光学顕微鏡により観察した。組織観察の結果、以下の点が明かとなった。 (1)結晶粒内のBi粒子については、熱処理時間が経過しても分布やサイズに殆ど明瞭な変化が見られない。 (2)結晶粒界の移動により、Bi粒子は粒界に吸収され、粒界上での"オストワルド成長"により、粗大な粒界析出粒子を形成する。 (3)粒界のBi粒子は、粒界と共に移動する。本研究では、今回の結果を説明するものとして、液相粒子中のAl原子の拡散を仮定した液相粒子の移動モデルを導いた。これより、液相粒子の移動速度vは、液相粒子中の溶質元素(Al)の拡散係数に比例し、液相粒子径に反比例する事が示された。

    III-V compound semiconductors (III=AI, Ga, In : V=P, As, Sb) have various outstanding properties which can not be obtained by Si semiconductor. Furthermore, mixture of these compounds which is called as III-V crystal alloy semiconductor gives possibilities to control its physical properties arbitrarily such as the band gap energy and the lattice constant by its composition. Therefore, III-V crystal alloy semiconductors are of great significance for opto-electronics and high-speed devices. In order to realize the desirable properties, i.e., to create the crystal alloy with appropriate composition by Liquid Phase Epitaxy (LPE) method under the condition of near phase equilibria, phase diagrams are indispensable for controlling their microstructures and compositions. However, it was reported that a thin epitaxial layer on a substrate exhibited completely different phase equilibria from those of bulk materials, for instance, deviation of equilibrium composition, formation of unexpected phases and so on. In this research, thermodynamic analysis on the phase equilibria of III-V crystal alloy semiconductor was carried out based on the thermodynamic data and experimental results. Then, thermodynamic database has been established for calculating the phase equilibria of both bulk and thin layer materials. Gibbs energies of the liquid phase and the compound are described by the sub-regular solution approximation and the two-sublattice model respectively. The strain energy was taken into account for calculating the stability of a thin epitaxial layer grown on a substrate. Thermodynamic parameters of eleven ternary systems have been evaluated and thermodynamic database for III-V alloy semiconductors has been constructed with or without taking account of a strain energy between a epitaxial layer and a substrate. The effect of the strain energy which is caused from the epitaxy between a crystal layer and a substrate can be seen, for instance, when a GaAs-GaSb crystal alloy is grown epitaxially on the (100) plane of lnP substrate. According to the result of calculations, unexpected homogeneous phase appears when its thickness is him and its composition is 5 lmol% GaAs which corresponds to the lattice matching composition. This is in good agreement with the experimental result of LPE by Quillec et al. The results of calculations for various combinations between thin layers and substrates show that phase stability of an epitaxial layer depends on the lattice constant and the crystal orientation of the substrate and on the thickness of the epitaxial layer.

    1. 目的: 最近のマイクロデバイス化の傾向の中、伝導電子のスピン依存散乱によって抵抗変化が生じるGMR材料が話題となっている。ホイスラー合金は強磁性元素を含まない合金ではあるが強磁性を示し、Cu基で規則変熊、2相分離変態が生じることが報告されている。したがってこれらの変態を利用することによりスピン依存散乱を生じさせ、GMR効果を発現できる可能性がある。一方Cu基以外のホイスラー合金としてAg_5MnAl合金があり、硬質磁性を示す非平衡相として長年注目されてきた。しかし、この合金を用いた磁気抵抗に関する報告はない。そこで本研究ではホイスラー合金を用い、組成、熱処理条件を検討することによりGMR効果発現の可能性について調べた。今年度は特にAg-Mn-Al系合金を中心に検討した。 2. 実験方法: Ag_5MnAlとAgを結んだ直線上の組成合金を選び、急冷薄帯を作製した。これらを473〜873Kにおいて熱処理した。磁気特性の測定にはVSM、相の同定にはDTAおよびX線ディフラクトメータ、磁気抵抗測定には手製の測定装置、組織観察にはSEM-EDX、TEMを用いた。 3. 結果: 得られた結果を要約すると以下のようになる。(1)as-spun状態では、Ag、γ、βMnの3相以外にもAg_<10>(Mn_<0.5>Al_<0.5>)_<90>急冷薄帯でε相、Ag_<40>(Mn_<0.5>Al_<0.5>)_<60>、Ag_<50>(Mn_<0.5>Al_<0.5>)_<50>急冷薄帯でτ相が出現した。しかしas-spun状態では全ての組成の急冷薄帯においてMR比は低く0.1%以下であった。(2)熱処理によりτ相の出現する組成域、温度域が変化するが、τ相の出現する組成域、温度域において高い磁気特性およびMR比が得られた。中でも573Kで168時間熱処理したAg_<40>(Mn_<0.5>Al_<0.5>)_<60>急冷薄帯において最も高いMR比0.9%が得られた。

    超塑性特性の発現手法の一つとして結晶粒の微細化が挙げられるが,高温下で微細な組織を維持するためには,分散粒子や第2相を利用して結晶粒成長を抑制する必要がある.これまで,粒子分散組織における結晶粒成長の遅滞は,Zenerの式により検討されてきたが,組織形態が大きく異なる2相混合組織や,さらに多相化した3相組織における結晶粒径を予測するには,より詳細な解析を必要とする.本研究では,それぞれの組織の特徴を考慮した結晶粒径の相関式を導出することを目的にして,2相混合組織は,α+γ2相鋼,α+γ2相ステンレス鋼,α+γCu-Zn系2相合金およびα+βCu-Al系2相合金を,また,3相組織はα+β+VCu-Al-V系3相合金に関する実験を行い,また,それぞれの組織について計算機シミュレーションを行い相関式の妥当性を検証した. (1)2相混合組織 分散組織における結晶粒成長の抑制効果については,Zenerによりピン止め力が評価されて以来,多くの研究が行われているが,本研究グループも分散粒子のピン止めによる粒界のたわみを見積もり,相関式R=4r/3f^<2/3>を導出した.一方,2相混合組織は,分散組織とは全く異なる組織形態を有するため,Zener流の解析の適用には限界がある.α+β2相混合組織における粒界の面積S=3(f_α/R_α+f_β/R_β)/2が,結晶粒のサイズを表すパラメータR=R_α+R_βが一定の条件で,最小になるような粒径の関係をラグランジェの未定係数法により求め,相関式R_α・f_α^<-1/2>=R_β・f_β^<-1/2>を導いた。この式は,2相混合組識における主相と副相の粒径相関式を示すが,実験およびシミュレーションの結果をよく再現している. (2)3相組織 2相混合組織における粒径の相関式は,副相の分率に関わらず成立するが,第3相としてV粒子が分散している場合には,主相の粒径は上式により表される副相による拘束とともに,分散粒子によるピン止めの影響を受けるため,両方の効果を考慮する必要がある.副相の分率が十分大きい場合には,主相の粒径は2相混合組織の相関式で表されるが,副相の分率が小さく,さらに,分散粒子によるピン止めが大きい場合には分散組織の相関式によって母相の粒径が定まることが実験により明らかになった.

    The shape memory (SM) effect due to the thermoelastic transformation has been investigated for 30 years, and it is generally noticed that the origin of the SM effect has been already clarified. Recently, we found in the Cu-Al-Mn alloys that a fully disordered bcc phase which transforms a disordered fcc phase shows an almost perfect SM effect. This result is peculiar against a common sense on the mechanism of the SM effect. The purpose of this study is to clarify an origin of the perfect SM effect of the disordered Cu-Al-Mn alloys by crystallographic and thermodynamic analysis. The Pbtained results are as follows : (1) The crystal structures of the parent and martensite phases have been determined. Alloys with high Al content over 17at% transform from the parent A2 (bcc) to martensite Al (fcc) structure, and those under 16at% transform from the L21 to 18R structure. (2) It has been clarified that volume change by the A2/A1 transformation is very small less than 1% and the transformation is thermoelastic. (3) The SM properties of many alloys have been examined. It has been clarified that the most alloys with the Al content over 14at% show an excellent SM effect. (4) A thermodynamic analysis of the stability of ordered phase has been performed Bragg-Williams-Gorsky model and pair interaction energies between Cu, Al, and Mn were determined. (5) Enthalpy changes due to short-range ordering have been estimated on the basis of the result of (4). It was clarified that values of the enthalpy changes are comparable to enthalpy changes due to the A2/A1 martensitic transformations. All these results suggest that the short-range ordering is enough to give a reversibility on the lattice correspondence between the parent and martensite lattices, resulting in the SM effect.

    Recently, a new type of process to fabricate high speed steels consisted of hyperfine grains together with uniformly distributed particles, which is called as carbide dispersion carburization (CDC) process, is proposed. In this process, the superior resistance to wear and the outstanding toughness can be obtained by carburizing C-free Fe base alloys with high contents of Ti, V,Mo, W etc.. In this study, an attempt by CDC process was made to produce high speed steels with very high hardness over Hv1000 on the basis of information of the calculated phase diagrams. The obtained results are as follows : (1) In order to establish a data base for estimating phase equilibria of the Fe-base multi-component systems, thermodynamic analysis of Fe-C and Fe-N base systems were performed. (2) On the basis of results of the thermodynamic analysis, microstructural evolution (including the kind, content and volume fraction of carbides appearing during carburizing and heat treatment) of Fe-V-Mo-C alloys was simulated. (3) Volume fraction, size and distribution of carbides in several Fe-V-Mo-C specimens with different composition produced by CDC process have been measured. The result of the examination suggests that the carbon content and the atomic ratio between V and Mo are the most important factors for determining the size and distribution of carbides. (4) On the basis of such the calculation and examination for the microstructural control, some alloys with suitable composition for obtaining both high hardness and toughness have been produced and examined. Consequently we could get some excellent alloys with hardness over Hv 1000. At the present, a cooperation project for practical applications with steel making companies is running.

    本研究では、鋼中のCuに起因した表面割れについての基礎的情報を得るため、Fe-Cu-X(X=V,Cr,Mn,Co,Ni,Al,Si,Sn)三元系における固液平衡を実験的に測定し、得られた結果に対して熱力学的観点から考察を行った。それにより以下の様なことが明らかとなった。 1.本研究で対象とした8元素のうち、V,Cr,Mn,Si,SnはFe中のCuの固溶度を減少させ、その傾向は、Snにおいて著しい。一方、Co,Ni,AlはCuの固溶度を増加させることがわかった。したがって表面割れの改善には、Co,Ni,Alの添加が有効と考えられる。 2.実験により得られた固液平衡の測定値をもとに、熱力学的解析を行った。CALPHAD法により、各2元系と3元系の熱力学パラメーターを評価しFe-Cu-X三元系状態図を作成した。これにより約1000〜1600°Cの温度範囲における固相と液相に関する相平衡を精度良く推定する事が可能となった。 3.合金元素の添加によるFe中のCuの固溶度変化△Cuを計算するための近似式を熱力学的に導出した。これを用いて、本研究で対象とした8元素以外の元素についてもCuの固溶度変化△Cuを推定した。その結果、△Cuは周期律に沿って系統的に変化し、Co,Ni,PdなどのVIII族元素の添加が最も効果的に△Cuを増加させることがわかった。

    結晶粒径の微細化が超塑性の発現を大きく左右することから本研究では,結晶粒微細化を目的として利用される粒子分散組織と2相混合組織における結晶粒の粗大化や安定性についてのコンピュータシミュレーションを行い,第2相による結晶粒成長の抑制効果を定量的に評価した. (1)粒子分散組織 分散粒子による結晶粒成長の抑制効果については,Zenerが1948年にピン止め力を定量的に評価し,母相結晶粒の平均粒径Rと第2相粒子の平均粒径rとの間にR=4r/3fの関係があることを提唱した.ここで,fは第2相の体積分率である.この式は粒子が組織中にランダムに分散し,そのとき粒界上にある粒子が一律にF_<pin>=πrσのピン止め力を粒界に及ぼすという仮定の元で導出されている.しかし,この式は,近年のコンピュータシミュレーションの結果や,実験データと一致しないことが指摘されている.本研究では,まず,Zenerによる上記の仮定の再検討を試みた.粒界が粒子によるピン止めを受けた際の柔軟性を120°の凹凸に評価し,そのときの粒界上の粒子数を見積もり粒径の相関式を以下のように導出した. R=(3πr)/(4f^<1/2>) (2次元) R=(4r)/(3f^<2/3>) (3次元) 2次元の式はシミュレーションの結果をまた3次元の式は実験値を良く説明できることが明らかとなった.

    1.Calculation of phase equilibria between austenite and complex compounds A thermodynamic model was presented to calculate the composition of austenite as well as that of complex compounds in the microalloyed steels containing Ti, V and Nb.Especially the phase separation of the carbonitrides were taken into account in the analysis. The effect of individual element was briefly summarized as follows : , (a)Ti addition to the microalloyed steels enhances the formation of Ti-rich nitrides mainly due to its extreme low solubility in austenite. (b)Complex addition of the elements bring the phase separation of the carbonitrides, and in almost cases the separation between NbC and VC or NbC and TiN is presented. This phenomena can be explained from the view points of the relative stability of binary compounds. 2.Effect of secondary precipitates on the morphology of MnS In order to control the morphology of MnS formed by solidification in steels and its modification by alloying of Ti, O,C and N,the concentraion, amount of secondary precipitates (oxides, carbonitrides) were investigated, in relation with phase equilibria.

    The residual Cu in steel made from ferrous scrap is well known to cause surface fissure during the hot roling process. When the concentration of Cu in the surface layr exceeds the solubility of Cu in solid Fe, nearly pure liquid Cu forms at the interface of steel and the oxides. The solubiliyt of Cu in solid Fe is one of the dominant factors of this phenomena. Therefore, the effect of allying elements on the solubility of Cu in solid Fe has been investigated by using solid-liquid diffusion couples. An addition of Co, Ni and Al results in an increase of the solubility of Cu, while that of V,Cr, Mn, Si and Sn decreases the solubility. Thermodynamic calculation of the solid/liquid phase equilibria in the Fe-Cu-X ternary system has been also performed, whire a set of thermodynamic parameters of solid and liquid phases has been evaluated. Furthermore, the equation that describes the change of the solubility of Cu in solid Fe with an addition of alloying elements has been derived by thermodynamic analysis of these experimental values

    Theoretical and experimental study of the effect of grain size on the grain boundary segregation was made and the results obtained are as follows ; 1.The equilibrium segregation of solute to the grain boundary can be described by the modified Mclean's equation : 2.The grain size effect on the intergranular segregation is remarkable with higher segregation energies and lower bulk concentrations with decreasing temperature. 3.When the segregation free energy of X is larger than that of Y in A-X-Y ternary alloy, the grain boundary concentration of X atom decreases with decreasing grain size, while that of Y atom depends on the bulk concentrations of solute. 4.An experimental evidence of the grain size dependence of the intergranular segregation in Cu-0.0015at.%Bi alloy was obtained. 5.The segregation energy of Bi in Cu was estimated to be about 62.5kJ/mol. 6.It is suggested that the grain size has a significant role on the grain boundary segregation not only in the metallic system but also in ceramics.

    The beta phase of nickel and cobalt aluminides with B2-type (C_sC1) structure have the potential to serve as a new type of materials with multi-functional properties such as high temperature strength, good oxidation resistance, shape memory, high damping capacity, stc. However the lack of ductility limits their application as the functional materials. The aim of this project is to develop a new type of beta base multi-functional materials improved ductility by microstructural control. 1.Thermodynamic Analysis The phase equilibria of the Ni-rich portion in the Ni-Al-Mn, Ni-Al-Co and Ni-Al-Fe systems have been experimentally determined, and thermodynamic analysis on basis of the experimental data have been done. 2.High Temperature Materials By means of microstructural control due to the information of the thermodynamic analysis, ductile gamma'(L1_2)+beta two-phase alloy which has both excellent oxidation resistance and high temperature strength has been developed by the conventional fabrication method combined with a thermomechanical heat treatment. 3.Shape Memory and Damping Materials Martensitic transformation temperatures in the beta phase B2*L1_0 (Ms) of the Ni-Al-X (X : Ti, V,Cr, Mn, Fe, Co, Cu, etc.) systems were determined by DSC.It was clarified that adding Mn, Fe and Co are useful to increase the Ms temperature. By means of these data of Ms and phase equilibria, ductile gamma(Al)+beta two-phase shape memory alloys which operate at high temperatures between 100 and 600゚C have been developed in the Ni-Al-Fe-Mn quaternary system. These two-phase shape memory alloys show not only high damping capacity, but also higher yield strength than the other damping materials.

    Ni-Al系及びCo-Al系に出現するCsCl型B2構造を有するβ相は、耐熱、耐酸化材料として有望視されていが、極めて脆いために塑性加工はもちろん機械加工も困難であった。最近、本研究グループは、β相(B2構造)にfccAl構造のγを少量混在させ、組織制御を行うことによって靭性が飛躍的に向上する事を見い出した。本研究は、以上の背景の下に、Ni-Al基及びCo-Al基のB2型金属間化合物の組織を制御する事によって延性を改善し、その高温用構造材料として適用するための基礎的研究を行う事を目的とし、以下の研究成果が得られた。 1、Ni-Al-Fe系及びNi-Al-Co系合金について、β+γ領域で熱間加工後、種々の熱処理を行うことによって、様々な分率のβ+γ'(L2_1構造)2相合金を作製できた。このようにして得たβ+γ'2相合金は、加工熱処理の違いにより、3種類のまったく異なった組織を呈し、特に、焼鈍後の焼き入れによりβ相がマルテンサイト変態を起こす合金では、その後の再熱処理により、ブロック状と微細なラメラ-状の2種の組織が現れることがわかった。この組織は、マルテンサイト相の規則化や不連続析出等の様々な変態が関与して生じたものであることが解明された。これらβ+γ'2相合金は、機械的性質にも優れ、特にラメラ-状の組織を有する合金は、良好な引張特性を有することがわかった。 2、Ni-Al系及びCo-Al系B2相は、高温強度に欠けているので、整合な析出相の利用が考えられる。そこで、高いクリープ特性を有すると報告されているβ+H(ホイスラ-規則boc相)2相組織について、その組織制御の基礎となる相平衡を実験的に明らかにした。

    To develop a new type of beta (NiAl : B2) -base superalloy, phase equilibria in the Ni-Al base systems have been investigated and some microstructural controls based on the information of the phase equilibria have been performed. The results obtained are summarized as follows. 1, Phase Equilibria in the Ni-Al Base Systems The phase equilibria among the beta, gamma (A1), gamma' (L1_2), beta' (L2_1) and eta (D0_<24>) phases in the Ni-Al-Ti, Ni-Al-Fe, Ni-Al-Co and Ni-Al-Ti-base systems were determined mainly by diffusion couple experiment. Thermodynamic analysis and computer calculation of phase diagrams of the Ni-Al, Ni-Ti, Ni-Al-Ti, and Ni-Al-Fe systems were also carried out. 2, Microstructural Control gamma+beta, gamma'+beta and gamma+gamma'+beta multi-phase alloys were obtained by a conventional thermomechanical treatment through the microstructural control. In the Ni-Al-Fe and Ni-Al-Co systems where martensitic transformation occurs in the beta phase, three types of beta+gamma' structures i.e.blocky, fine lamellar and widmanstatten structures, can be obtained. 3, Mechanical Properties of Multi-Phase Alloys (1) gamma+beta two-phase alloys ; the introduction of gamma phase improves the ductility drastically and exhibits a good tensile properties at room temperature. This type of alloys shows an excellent oxidation resistance, while high-temperature strength decreases with increasing temperature over 600゚C. (2) gamma+beta two-phase alloys ; the alloys with the lamellar structure show an excellent mechanical properties at room temperature. The high-temperature strength is slightly higher than that of the gamma+beta two-phase alloy. (3) gamma'+beta+beta' three-phase alloys ; Ni- (15-25) Al- (7-15) Ti base three-phase alloys exhibit an excellent strength higher than that of some practical superalloys at the temperatures below 700゚C,while the increase in ductility is necessary for the practical use. It is concluded from the present study that the Ni-Al base superalloys with the beta matrix have sufficient oxidation resistance and exhibit strength higher than many practical superalloys at the temperatures below 700゚C.

    次期耐熱材料として盛んに研究がなされている金属間化合物は、一般に延性に乏しく、そのことが実用化への最大の障害となっている。単相では脆い材料も、多相化することにより延性の改善が得られる場合も少なくない。本研究では、高い融点と優れた耐酸化性を有するNi-Alβ相を主相とする多相合金を作製し、組織と機械的性質の関係を明かにした。 本年度は、Ni-Al-Fe系、Ni-Al-Co基系におけるβ+γまたはβ+γ'2相合金の組織と熱間加工性、機械的性質との兼ね合いについて研究をおこなった。同時に、Ni-Al-X系の状態図を作成し、次の点が明かとなった。 (1)鋳造組織と熱間加工性について a、β中にわずか数%のγ相が存在するだけで、加工性が飛躍的に向上する。 b、鋳造組織が、等軸晶の場合に加工性が良好となる。 c、γ'相の存在によって、熱間加工性は著しく劣化する。 (2)組織と機械的性質について a、γ相がβ相の結晶粒界にフィルム状に存在する場合に、6%以上の引張伸びが得られる。 b、Ni-Al-Fe系、Ni-Al-Co系では、β+γ'2相組織であっても良好な伸びが得られる。 c、状態図の情報を活用することによって、高温でβ+γ2相として熱間加工を行い、中温度で時効することによって組織をβ+γ'2相に制御できることを見いだした。この場合、マルテンサイト変態と規則-不規則変態の利用によって、極めて微細な組織を得ることが出来る。

    The control of morphology of the interface between different phases is one of the key technology in producting composite materials. In the present work, the phase interfaces in Ti-X, Fe-C base and Ni-Al base systems have been studied from the viewpoints of both the experimental and thermodynamics. (1)alpha/beta interface in Ti-X system : In rge alpha/beta diffusion couples of Ti-X alloys, non planar interfaces were formed for Fe, Co and Ni. This result might due to high speed diffusion of these elements in alpha solid solution. (2)alpha/gamma interface in Fe-C-X system : The alpha/gamma interfaces formed by carburization in Fe-C-X (X : Ti, V, Nb, Ta, Cr, Mo, W, Co and Cr) alloys were stable, while non planar interfaces were observed for P, Al, Sb, Ni, Mn, Si and Ge. These results could be explained quantitatively by the concept of the local equilibrium. (3)Pseudo-interface in beta phase of Ni-Al base diffusion couples : In a single phase region of beta phase in the Ni-Al base couples, an interface which has a clear concentration drop was observed in the concentration profile. This is due to the anomalous variations in diffusion coeffecients in B2 structure arising from its composition dependent defect structure.

In this work, we have tried to enhance the strength, ductility and hot workability of the Cu-Mn-Al alloys by microstructural control based on information of phase diagrams. (1)Phase equilibria in Cu-Mn-Al system : Phase equilibria among alpha, beta and gamma phases at 500。C, 600。C, 700。C and 800。C were determined. It was clarified that addition of Mn stabilizes the beta phase.

In the non-stoichiometric region, it was shown that the alloys have good mechanical properties with elongation of (3-21)%, 0.2% proof strength in the region of (500-700)MPa and tensile strength in the region of (700-1010)MPa.

    In order to develop the Ni-Al base shape memory alloys with enhanced ductility, the hot workability, microstructure, shape memory effect and mechanical properties in the Ni-Al-Fe, Ni-Al-Mn and Ni-Al-Fe-Mn systems were investigated. The results obtained are as follows : (1) A small amount of fcc phase formed by the addition of Fe and Mn has a drastic effect not only on the hot workability but also on the tensile ductility at room temperature. The enhancement in ductility is mainly due to the modification of beta-phase grains by the coexistence of phase. (2) Ductile shape memory alloys based on the bate phase matrix in the Ni-Al-Fe, Ni-Al-Mn and Ni-Al-Fe-Mn systems have been developed by promoting the formation of fcc phase in the grain boundary of matrix phase. The two-phase beta+gamma alloys show high degree of shape recovery, which depends on the volume fraction of the phase. Normal pseudo-elastic behavior above Ms is not detected unambiguously in these alloys. (3) The transformation temperatures can be controlled by adjusting the annealing temperature in the beta+gamma two-phase region. The maximum operating temperatures for shape memory alloys in the Ni-Al-Fe and Ni-Al-Mn systems are 150゚C and 700゚C, respectively. (4) Although these alloys have not shown in the complete shape recovery, they are attractive for the new type of shape memory alloys which operate at rather high temperatures.

    The purpose of the present research is to analyze the phase equilibria between the carbonitrides in microalloyed steels and to develop a method to calculate the complicated phase relationship. 1.Miscibility gaps in some transition-metal carbide or carbonitride systems have been experimentally studied. The systems investigated were (V,Nb)C, (Ti,V,Nb)C, (V,Nb)C, (V,Nb)(C,N), (Ti,Nb)(C,N)and(Ti,V)(C,N),and the equilibrium compositions were determined by the X-ray measurements and EDX analysis. A thermodynamic calculation of the miscibility gaps was performed on the basis of the experimental results. The Gibbs energy of the carbonitrides has been described using a sublattice model and the interaction energies in the pseudobinary systems were estimated from the difference in lattice constants in components. The miscibility gaps in the 20 (X,Y,Z)C types of carbides,10 (X,Y,Z)N types of nitrides and 10 (X,Y)(C,N) types of carbonitrides were calculated. 2.A thermodynamic model was presented to calculate the composition of austenite as well as that of complex carbonitrides in the microalloyed steels containing Ti,V and Nb. The thermodynamic model was applied to the phase equilibrium calculation between the austenite and (Ti,V,Nb)X, (M1,M2)(C,N),or(Ti,V,Nb)(C,N) type of compounds. Some variations of precipitation mode were observed through the calculation according to the alloy contents and kinds of additional elements. The effect of individual element was briefly summarized as follow;(a) Ti addition to the microalloyed steels enhances the formation of Ti-rich nitrides mainly due to its extreme low solubility in austenite. (b)Complex addition of the elements brings the phase separation of the carbonitrides,and in almost cases the separation between NbC and VC or NbC and TiN is presented. This phenomena can be explained from the view points of the relative stability of binary compounds.

    異種材料の接合界面の形態は、材料の特性に大きな影響を及ぼすので、界面の形態的特徴を理由づける成長機構を明確にする事が、複合材料の研究開発に重要である。本研究では、耐熱材料の主流であるNi基超合金のコ-ティング相と基材との界面に注目して、NiーAlーX系のβ相(B2)とγ相(fcc)を接合した場合に生じるγ′(Ll_2)/γ及びβ/γ界面の形状について拡散対による実験を行い、その形状を支配する因子について検討を行った。 1.γ′/γ異相界面の状態: NiーAlーX系(X:Co、Cr、Cu、Fe、Mn、Mo、Nb、Si、Ta、Ti、V、W)は、Cr及びFeを第3元素として添加した場合に凹凸のある不安定界面となった。この場合のγ′相及びγ相間の相平衡は、CrとFeの添加量が増すほど両相の単相域が狭まり、かつCrとFeはγ相に濃縮するという状態図的な特徴を有している。この様な不安定界面の成因は、反応中の界面に生成する突起の内外での組成分布と、それに従った各成分元素の拡散方向を考えることにより説明できる。 2.β/γ異相界面の形態: β相とγ相とが広い組成範囲で直接平衡を示すNiーAlーCo系、NiーAlーFe系、NiーAlーMn系について作成した拡散対のβ/γ界面は主に、β+γ2相域のタイラインを横切る様な組成の組合せの場合に不安定化した。この場合、状態図的な特徴よりも母合金の組成の組合せが重要であり、拡散対中の組成分布を状態図上にプロットした拡散経路と、2相領域の相境界線及びタイラインとの幾何学的関係によって説明できる。

    今年度は、以下についての研究を行った。 1.Ni-Al-X系におけるγ'/β界面の状態と添加元素Xの分配挙動について:Ni-25at%Al(γ'相)とNi-50at%Al(β相)に第三元素(Ti、V、Cr、Mn、Fe、Co、Cu、Mo、W、Nb、Ta)を適量添加し、高温圧接により拡散対を作製した。この拡散対を900〜1300℃で熱処理し、γ'相とβ相の界面の形態を光顕観察した。その結果、Cr、V、Mn、Fe、Co、Cu、Siを添加したものはγ'/β相界が平滑(安定界面)であったが、Mo、Nb、Ta、Ti、Wを添加したものは平滑ではなく;凸凹のある乱れた界面(不安定界面)となることが明らかになった。この界面について、電子顕微鏡で界面近傍のγ'相とβ相の方位関係を調べたところ、BCC/FCC間の析出に見られるKurdjumov-Sacksの関係であることがわかった。また、γ'相とβ相に対する添加元素の分配を実験的に明らかにした。 2.Ni-Al-X系におけるγ'/β平衡と界面状態の関係:乱れた界面を生じさせるNi-Al-X系状態図の特徴として次の点が挙げられる。(1)γ'/β界面を乱す添加元素Xは、β相よりγ系相へ多く分配する。(2)γ'/β界面が乱れるNi-Al-X系の状態図では、X元素の添加によりγ'相もβ相も共に単相域が狭められる。以上のようなγ'/β両相へのX原子の分配挙動によって、界面凹部におけるγ'相内のAl原子の濃度分布が逆勾配となり、β相の成長が制御される。その結果、凸部と凹部における成長速度の差異がさらに助長されて界面の不安定性がますます激しくなると考えられる。以上のような状態図に基づく説明により、拡散対内の不安定界面の生成原因を解明した。

    The gamma (disordered fcc) and gamma' (ordered Ll_2 structure) phases are major constitutions in the Ni-base superalloys, while beta (ordered B2 structure) phase is used for surface coating. In spite of practical importance, however, the effect of alloying elements on the relative stability between gamma, gamma' and beta phases bas not been well established. The purpose of the present study is to clarify the partition behavior of alloying elements between gamma, gamma' and beta phases. Thermodynamic analysis of phase equilibria was also done by using regular solution approximation of gamma phase and sublattice model for gamma' and beta phases. The results obtained are as follows. 1. The phase equilibria of gamma, gamma' and beta phases in the Ni-Al-X (X: Si, Ti, V, Cr, Mn, Fe, Co, Cu, Nb, Mo, Ta, W) systems were accurately determined between 700 and 1300゚C. 2. The partition behavior of alloying elements can be classified into 6 categories. 3. The gamma phase is stabilized by alloying of Cu, Co, Fe and Cr, while Mo, W, V, Ti, Nb, Ta and Si stabilize gamma' phase and Mn stabilizes beta phase. 4. The Gibbs energy of ordered gamma' and beta phases can be well described by the sublattice model. 5. The thermodynamic parameters in the gamma, gamma' and beta phases were evaluated. 6. The phase equilibria of Ni-Al-Fe, Ni-Al-Ti, Ni-Al-Cr and Ni-Al-Mn systems are computed in the Ni-rich portions, which would be most useful for the design of microstructures in the Ni-base superalloys.
