    We aimed to establish the theory of microwave-accelerated solid-solid and solid-gas reactions. We established a methodology to observe the local thermal non-equilibrium on the surface or in the bulk of solids under microwaves. We succeeded in developing in situ measurement instruments for direct observation of local temperature and structure of materials during microwave irradiation using XAFS, Raman, light emission spectroscopy coupled with a high resolution thermography. We demonstrated that the formation of a local high-temperature is the key mechanism that microwaves accelerate chemical reactions. Furthermore, we clearly showed that this method could be used to control solid catalytic reactions and synthesis of new solid materials.

    Au films were deposited on SiO2 substrate (the microwave heating of which can be ignored) by sputtering with thickness of several 10~ 100nm. Then post annealing was performed with 5.8GHz single mode microwave applicator. And imposition of static magnetic field was performed, simultaneously. Nano structure observation by means of AFM and spectrum analysis of the film roughness wave number were conducted. It was shown that grain growth of bump crystals was sustained by the field imposition, and it is effective for improving the flatness of the film.

    In this research, vermiculite was selected for a specimen as one of layered silicate salts. Vermiculite was suspended in water and Cs was doped. Various salts were mixed with the Cs-doped vermiculite in solid (powder) state and microwave was irradiated, which was found effective for Cs removal. Addition of KCl and CaCl2 was effective for the ion exchange of Cs. And it was found that microwave heating has better removal effect than by an electric furnace below 700oC. It was also found that addition of these salts increases the permittivity and electric conductivity, which is related with the better microwave heating characteristics. Further addition of CaCO3 improves the removal effect, however, microwave heating became less easy.

    本研究は、マイクロ波加熱を利用して、金属酸化物を直接金属と酸素に分解することにより、二酸化炭素を発生せず、また酸素を発生させるプロセスを開発する事を目的とした。このためには、十分強力なマイクロ波(2kW)を用い、この電磁場を集中して印加できる2.45GHzマイクロ波シングルモード装置を用いて、Fe_3O_4をそのまま加熱する事により、FeOを生成させる事が可能である事が分かった。またFe_3O_4の加熱を利用してFe_2O_3をFe_3O_4に変換できる事も分かった。当初計画してた、電気化学的な還元反応を使う必要がなく、高温加熱プロセスでFeOまで作製する事都ができた。 加熱試料は、マイクロ波吸収が殆ど生じないCaO系の耐火物内に挿入し、マイクロ波磁場を集中して印加した。電気伝導性を有する鉄酸化物においては表面から誘導電流が生じるため、効率良く加熱する事が可能であった。本研究においては、これらにより加熱した試料がどのようなして有効な還元(分解)が可能であるか、加熱温度、必要マイクロ波入力、処理時間、固体/融体における還元速度など基礎的実験条件を設定することができた。また実験で得られた試料に関しては、微視的な観察を行い結晶相同定や、存在形態の解析を行った。 産業界においては製鉄業は二酸化炭素排出量が多いが、本研究結果は今後CO_2排出削減のための基礎技術として注目される日が来ると考えられる。また本研究は、含水低品位鉱石の処理にも応用できる可能性があり、今後の更なる検討が期待される。

    Electromagnetic separation technique of nonconductive particles from liquid metal was applied to fabricate a partially reinforced MMC of aluminum by ceramic particles, which has a high wear resistance and a good deformability. To separate particles, a high frequency magnetic field was imposed on an aluminum melt suspending silicon carbide (SiC) particles of which mean diameter was about 20μm. Suspended SiC particles were found to be transferred to the vicinity of the crucible wall in several ten seconds. The thickness of the particle accumulated layer (PAR) and the particle density could be changed by frequency (30-200 kHz) and current (42-163 A) in the ranges from 0.6 to 1.5mm in thickness and from 0.05 to 0.22 in particle density. The thickness of PAR was large in the middle of the aluminum cylinder, however it was very thin near the free surface and the bottom where the existence of strong liquid flows were predicted by the numerical simulation of turbulent flows in liquid aluminum. In order to obtain thicker PAR needed for brake materials, e.g.4mm, a 3-kHz generator was applied, which was expected to achieve thicker PAR because of its large skin depth, 4.7mm. However, intensive electromagnetic stirring prohibited particle separation. Numerical simulation revealed that the lift force generated in a velocity gradient near the wall prevented particle accumulation. By this simulation, the vertical distributions of the PAR thickness at different frequencies were well reproduced and the PAR formation was predicted for the case of 3kHz if the vertical profile of electromagnetic force was reformed to be uniform. Based on such prediction, molybdenum rings were placed near the free surface and the bottom to reduce flow strength there. However, improvement was not enough, though thin PAR was observed partly. A pulse imposition of magnetic field was tested aiming the reduction of flow strength without change in electromagnetic separation force. As a result, homogeneous PAR was obtained though the thickness was about 1mm. It should be noted that the particle density in PAR was more than 50 %, which was extraordinary comparing with the other results, less than 20%. Finally, the deformability and the strength of wear resistance were measured and the applicability of the present particle-reinforced MMC was confirmed.

    In this research, difference in film microstructures between in a homogeneous magnetic field and in a gradient magnetic field was investigated. Position of the substrate was modified to be variable in the apparatus already installed. Under condition of maximum80T^2/m of the field gradient, film was deposited and the weight change of FeCl_3 powder was measured. The followings points were clarified. 1.Cubic shaped, (100) oriented island crystals have higher probability of formation by imposition of gradient field, which is the same tendency as that of homogeneous field. 2.The magnetic field imposition effect was obviously observed in the flatness of the crystal grains on the film surface. It was demonstrated that the grains with flatter surface grain facet was obtained thn the one deposited by homogeneous field imposition. 3.The consumed amount of FeCl_3 source positioned in a gradient field was increased as an increase of the field intensity. The gas flow simulation in the reactor was performed in order to verify the third finding, by means of a software "Fluent" for fluid flow calculation. In the simulations of the gas flow, variations in gas properties, magnetic properties with temperature were taken into consideration, and the measured values of wall temperature distribution were input. It was shown that gas velocity at the outlet of the reactor increased doubly by the field imposition within the experimental conditions tested. In this study, basic simulation method for investigating the effects of the gas concentration distribution were established for the future studies.

    In this research, CVD reaction system of reducing iron chloride (FeCl_3) with hydrogen (H_2) was utilized. During the CVD process, steady magnetic field was imposed. Fist of all, fundamental deposition conditions were determined by imposition of 0.5T with non-superconducting magnet, then the microstructural characterization methods were established, such as XRD, TEM and FE-SEM. In the second stage, CVD apparatus was placed in the superconducting magnet installed in High Field Laboratory for Superconducting Materials, Institute for Materials Research, Tohoku University. Fabrication of Fe films and characterization of their microstructure and crystal orientation were conducted. The obtained results are summarized as follows : 1. It was found that the vaporized amount of FeCl_3 increased as an increase of magnetic field intensity. Especially, this tendency was obvious above 5T. 2. Island-shaped crystals are formed first, then the films are formed through their coalescence occurs. This type of the growth mode might be due to difficulty in nucleation of Fe crystals on an amorphous SiO_2 substrate. 3. Fraction of cube-shaped island-shaped crystals increased, as an increase of magnetic field intensity. Simultaneously, degree of (100) orientation increased, which is consistent with the easy- magnetization axis of iron crystals. The preferred nucleation might be induced by the imposition of the magnetic field. 4. Degree of (100) orientation decreased when island-shaped crystals changed to films. The films have Zone III grain structure because of the relatively high substrate temperature (〜0.5Tm of Fe). Occurrence of considerable grain boundary migration in the films might be related to the disappearance of (100) texture.

    本研究は、金属試料の加熱または冷却時の熱の出入りから変態率の経時変化と変態熱を同時に求め得る方法を考案し、これをTiNi形状記憶合金線状試料の変態熱測定に適用するもので、変態中の試料には応力を加えることができる新しい方法である。 本実験では直径1mmの線材試料を低温に保った窒素ガス中に設置し、直接通電することにより加熱する。そしてその試料温度の経時変化を正確に測定するとともに、その際の試料長さの変位量測定も行った。なお本年度は、試料から熱電対へ奪われる熱量を最小限に抑えるため、試料に取り付ける熱電対の径を細くし、精度の向上を図った。 変態実験に先立ち、比熱が既知で無変態の18%Cr-8%Niステンレス試料を用いた実験を行い、装置特性である伝熱係数を求めた。 変態実験はTi-50.2%Ni形状記憶合金試料を用いて行った。TiNi合金は、昇温時にオーステナイト変態が起こるため、昇温速度が減速する。この減速に使われる熱量から、変態熱・変態率を求めた。実験では、試料下部に荷重をかけ、応力負荷による影響も調べた。 まず本実験から得られた変態温度範囲と示差熱分析結果とを比較し、本実験の妥当性を確認した。 試料に通電する電流値は、変態挙動に影響を与えないことがわかった。 試料に負荷する応力の増加とともに変態温度域は高温側へ移行し、試料長さの変位量も大きくなった。この変位による仕事量は変態熱に比べて小さく、変態熱への影響はわずかだった。 応力負荷時に熱サイクルを与えることにより変態温度域は低温側へ移り、試料全体の長さは徐々に伸びた。この熱サイクルにより変態熱は小さくなる傾向がみられ、すべり変形に伴い試料内に導入される転位が応力誘起変態と密接な関係を持つと考えられる。また熱サイクル数の増加とともにこれらの傾向は小さくなり、収束する傾向がみられた。

    This study was intended to fabricate high strength ZrO_2/MoSi_2 composites, which took advantage of transformation toughening. Chemical-Vapour-Infiltration(CVI) method was adopted for incorporation of ZrO_2 into partially sintered MoSi_2. In order to obtain fundamental knowledge for fabrication process and the microstructure of the composites, ZrO_2 were deposited with no additive oxides. Microstructures of post-annealed ZrO_2 were observed and the optimum annealing conditions for realizing transformation toughening were discussed. The following results were obtained. 1) Fine MoSi_2 grains were well-covered with CVI-ZrO_2 by using Metal-Organic(MO) precursor. 2) The infiltrated ZrO_2 were all amorphous, therefore post-annealing treatment was required. The post annealed ZrO_2 at 1073K for 3.6ks in air consisted of equi-axed grains of several 10nm in diameter. Existence of monoclinic ZrO_2 was observed and this microstructure suggests the limitation of annealing conditions. 3) Hardness increase was realized by increase of ZrO_2 into MoSi_2 and maximum hardness of 20GPa was obtained in the composites. High toughness was recognized by Vickers indentation and occurrence of transformation toughening was realized.

The microstructures of the as-deposited and post annealed films were observed in concerning of the grain structure, formation of ternary nitrides. Properties of the composite films were investigated. The following results were obtained : 1) Growth rate and film compositions of the composite film deposited in the downstream region were expressed by ratio of the single TiN and AlN film growth rates. 2) Mass transfer model was proposed for predicting the TiN and AlN film growth rate distributions. The model successfully expressed the growth rate distributions in the reactor along the axial direction for different deposition conditions. 3) TiN and AIN grains having several nm to several tens of nm existed neighboring with each other, the configuration of which made the grain growth difficult to occur. Formation of Ti_2AlN was confirmed by annealing the film at 1273K. 4) It was observed that oxidation resistance increased by addition of AIN.The composite film had larger hardness than the each films and the post annealed films had the hardness maximum at the composition of Ti/A1-2

    Al/Al_2O_3複合体をSiO_2と融体Alとの置換反応により作製する方法においては、任意形状のSiO_2をそのままの形でAl/Al_2O_3複合材料に変換できる点において特徴がある。本材料の機械的性質は製造温度により変化し、主に反応温度1273K付近を境に材料硬度が変化する。低温度では硬く脆い材料が得られ、高温度では延性が増加することを見出している。本研究においては反応温度の制御により複合材料硬度の傾斜化を行うことを目的とし実験を行い以下の結論を得た。 1、Al浴に直径浸15mmのSiO_2棒を浸漬した状態で浴温度を1073Kと1373Kとの間において変化させた。温度を上昇させた場合、半径方向に硬度変化は生じなかった。一方温度を低下させた場合、最終反応部である棒中心部において硬度を1.3倍程度高めることができた。 2、浴温度を低下させるとともに、試料を挿入することにより試料長手方向に硬度を2倍程度変化させることができ硬度を大きな傾斜化が得られることができた。 3、Al浴に浸漬し、温度を変化させただけでは、低温アルミナ相を含有する高硬度を有する複合組織を生成することが不可能であった。浴温度を上昇させる場合、低温アルミナ相を加熱すると高温相に変態し、また材料組織の粗大化が生じ、硬度が低下したためである。また浴温度を低下させた場合では、十分な大きな冷却速度がないと上述の高硬度組織が形成されないためである。一方、試料の移動と浴温度の低下を並行することによりこれが可能となり、2の結果が得られたものと考えられる。

    ZIRCONIA HAS POLYMORPHS OF CUBIC, TETRAGONAL AND MONOCLINIC PHASES FROM HIGH TO LOW TEMPERATURES. WHEN IT IS ALLOYED WITH YTTRIA, LIME OR MAGNESIA, THE HIGH TEMPERATURE PHASES ARE STABILIZED BY THE INTRODUCED OXYGEN VACANCIES. IT IS INTERESTING THAT ZIRCONIA IS STABILIZED BY CERIUM IN SPITE OF THE SAME VALENCE AS ZIRCONIUM. THE PRESENT INVESTIGATION CONSISTS OF TWO PARTS AS FOLLOWS. (1) THE PHASE DIAGRAM OF ZIRCONIA-CERIA SYSTEM WAS DECIDED EXPERIMENTALLY. THE ARCMELTED LOW CERIA ALLOYS WAS TETRAGONAL PHASE CONTAINING TRANSFORMATION TWINS AND DOMAINS LIKE LOW YTTRIA ALLOY, BUT COHERENT PRECIPITATION TAKES PLACE IN THE STEAD OF SPINODAL DECOMPOSITION. (2) THIN FILMS OF ZIRCONIA ALLOYS CONTAINING YTTRIA FROM 2 TO 8 MOL% WERE PREPARED BY MEANS OF RF-SPUTTERING. THE GRAIN SIZE WAS ABOUT 20 NM. THE TETRAGONAL PHASE IN 2 AND 2.5 MOL% YTTRIA ALLOYS WAS TRANSFORMED TO MONOCLINIC PHASE BY AGING AT 200 ゜C AGING, BUT CUBIC PHASE WAS STABLE TO THIS AGING.

    <ZrO_2> HAS POLYMORPHS OF CUBIC,TETRAGONAL AND MONOCLINIC PHASES FROM HIGH TO LOW TEMPERATURES WHEN <Y_2O_3> IS ADDED, TETRAGONAL PHASE CAN BE OBTAINED AT ROOM TEMPERATURE,AND SHOWS VERY HIGH TOUGHNESS AS THE RESULTS OF STRESS INDUCED TRANSFORMATION FROM TETRAGONAL TO MONOCLINIC ACCOMPANYING WITH VOLUME EXPANSION. THIS CERAMICS IS CALLED PARTIALLY STABILIZED ZIRCONIA, "PSZ". SIMILAR TOUGHNING MECHANISM CAN BE FOUND IN STEELS. IN THIS STUDY, THE TOUGHENING TECHNIQUES DEVELOPED IN THE FIELD OF STEELS ARE APPLIED FOR THE TOUGHENING OF CERAMICS,ESPECIALLY PSZ. AT FIRST, ZIRCONIA-YTTRIA PHASE DIAGRAM WAS INVESTIGATED BY MEANS OF DILATOMETRY AND EPMA. AND NEW DIAGRAM WAS PROPOSED. THE SHAPE OF SOLUBILITY LINES IN THIS DIAGRAM IS VERY CHARACTERISTIC. THE REASON WAS CONSIDERED AND IT WAS CONCLUDED THAT THE TETRAGONAL-CUBIC TRANSFORMATION WAS A PARA-FERROELASTIC SECOND ORDER TRANSITION AND TETRAGONAL PHASE COULD BE TRANSFERED CONTINUOUSLY TO CUBIC PHASE WITH INCREASING EASING <Y_2O_3> CONTENTS. FROM THESE NEW ASPECTS ON THE PHASEDIAGRAM, THE FORMATION MECHANISMS OF VARIOUS MICROSTRUCTURES INCLUDING DOMAIN,MARTENSITIC STRUCTURES, ANTI-PHASE BOUNDATIES IN QUENCHED SPECIMENS AND SPINODAL DECOMPOSITION IN ANNEALED SPECIMENS WERE DISCUSSED,AND THEN THE TOUGHENING PROCESS WERE TRIED ON PSZ.
