    Abstract

    The Ni concentration and temperature dependence of the lattice parameters of the B2 and B19′ phases in binary Ti–Ni alloys was systematically clarified near the martensitic transformation temperatures, using samples with finely varied Ni concentrations ranging from 50.00 to 51.00 at.%. The differences between the present data and previously reported values were quantitatively explained and reinterpreted in terms of uncertainties in Ni concentration, measurement conditions, thermal history, and extrapolation methods. Furthermore, based on the lattice parameters obtained in this study, the effect of Ni concentration on the suppression of transformation-induced dislocations and the stabilization of thermal cycling behavior was discussed in terms of geometrical incompatibility. From the perspectives of composition increment, temperature steps, consistency in thermal history, and transparency of extrapolation procedure, the present dataset is considered to be among the most accurate, precise, and consistent lattice parameter datasets currently available. This dataset provides a highly reliable basis for evaluating the variation in lattice parameters among literature and serves as a foundation for future investigations into phase transformation behavior in Ti–Ni alloys.

    Methods of fabrication by centrifugal casting for functionally graded materials (FGMs) can be classified into two categories on the basis of the relationship between the process temperature and the liquidus temperature of a master alloy. They are the centrifugal solid-particle method and centrifugal in situ method, which could be carried out at process temperatures lower and higher than the liquidus temperature of the master alloy, respectively. In a previous study, it was found that the microstructures of Al–Al<inf>3</inf>Ti FGMs fabricated by the centrifugal in situ method processed at 1600 °C were different from those fabricated by the centrifugal solid-particle method processed at 800 °C. Although it is expected that the FGMs fabricated by the centrifugal in situ method processed at approximately the liquidus temperature should show extraordinary microstructures, those microstructures have not been observed. In this study, the microstructures of Al–Al<inf>3</inf>Ti FGMs fabricated at 1000 °C (centrifugal solid-particle method) and 1200 °C (centrifugal in situ method) were investigated.

    Al matrix functionally graded materials (FGMs) with oriented Al<inf>3</inf>Ti platelets were fabricated by a centrifugal solid-particle method. The applied centrifugal forces were 30, 60, and 120G (units of gravity). The orientation and volume fraction gradients of the Al<inf>3</inf>Ti platelets within the samples were measured. Since a good lattice correspondence was reported for the close-packed directions and the close-packed planes between Al and Al<inf>3</inf>Ti, the Al matrix in the Al–Al<inf>3</inf>Ti FGMs fabricated by the centrifugal solid-particle method should have some texture. Al matrix texture was, therefore, analyzed by electron back-scattering diffraction (EBSD). Analysis of the resulting pole figures indicates a preferred orientation along the (200) plane for the Al matrix crystals. Furthermore, increasing the applied centrifugal force enhances the orientation effect. A correlation appears to exist between platelet orientation and the preferred texture of the Al matrix.

    Strain-rate sensitivity (SRS) and shape memory effect were investigated in Ti-Cr-Sn β(bcc)-Ti shape memory alloys using strain-rate dip test. There was a trade-off relation between shape recovery strain and SRS. This means that SRS becomes more significant, whereas the shape recovery strain decreases with increasing Cr content. This change in SRS is considered to be a transition of deformation mechanism from non-thermal activation process to thermal activation process with increasing stability of β phase.

    Although NiTi shape memory alloys are used extensively as biomedical applications such as stents and orthodontic wires, Ni is known as a toxic metal element. Thus, development of Ni-free shape memory alloys is required for biomedical applications. A candidate is Ti-base shape memory alloys. Although shape memory effect of Ti-Nb alloys has been widely investigated, comparably limited data has been obtained for Ti-Mo base alloys. It is known that the martensitic transformation temperature (M_S) from β parent phase to α" martensite phase is much lowered by Mo addition than by Nb addition, whereas few studies exist about the effect of ternary additions on M_S of Ti-Mo alloy. In order to clarify the effect of ternary additions on shape memory effect and mechanical properties comprehensively, Ti-Mo base alloys containing 3d transition metal elements were systematically investigated in terms of phase constitution and mechanical properties. It was found that the addition of 3d transition metal elements reduces M_S of the α"-martensitic transformation, and that all the ternary additions suppress the formation of the ω-phase which causes embrittlement. No alloy exhibited clear superelasticity. 1mol% addition of these 3d transition elements improves both the strength and ductility. Further additions of Co and Ni degrade the ductility due to large hardening. However, only Fe addition clearly improves strength without lowering ductility. Thus, Fe addition is effective to improve mechanical properties of Ti-Mo alloys.

  • DMA Evaluation of Damping Properties of Shape Memory Alloys

    Dynamic mechanical analysis (DMA) is a method to clarify the mechanical behavior of a sample depending on temperature, load and frequency, and DMA can evaluate Young's modulus, storage modulus and loss modulus, damping and internal friction. Shape memory alloys (SMAs) are expected to be new damping materials since SMAs are in general believed to possess large damping due to their stress-induced martensite transformation (SIMT) and/or reorientation of martensite variants. Details of damping properties of SMAs however, are still insufficiently studied under a large strain condition. In this paper, DMA was utilized for the characterization of shape memory behavior and damping properties of several Ti-Ni base SMAs containing platinum-group metals (PGMs) such as Rh and Ru. It was found that Rh addition reduces both Young's modulus and martensitic transformation temperatures of TiNi, and that Young's modulus is low around martensitic transformation temperatures. Besides, frequency dependence on internal friction was observed below martensite transformation finish temperature : internal friction becomes larger with lowering when martensite phase is stable. Moreover, PGM-added Ti-Ni SMAs commonly exhibit larger internal friction than binary TiNi. It is concluded that PGM-added TiNi SMAs can be applicable for damping uses and that DMA is a quite useful evaluation method for damping properties of SMAs.

    形状記憶合金はゴムのようにしなやかに変形する「超弾性」と、加熱で元の形状に戻る「形状記憶効果」を発揮しますが、形状記憶効果は繰り返し駆動にともなう機能劣化が早く、社会実装があまり進んでいません。本提案では、合金内部に存在する「ねじれ」を制御して損傷発生を抑制し、繰り返し動作時にも高出力を安定的に維持する材料設計法により、安価な元素を用いた低コスト、鍛造可能かつ長寿命な新形状記憶合金「ウルトラニチノール」を開発し、これまで適用が難しかった分野での利用を目指します。これにより、熱アクチュエータの小型化・省エネ化が進むとともに、新たな応用可能性が広がり、環境負荷低減やSDGsへの貢献が期待されます。

    In shape-change materials such as shape memory alloys and piezoelectric materials used for medical and energy applications, external fields such as force and magnetic field and material functions are deeply related each other。 The origin of the shape change is the domain rearrangement and phase transformation due to the motion of domain homo interface. In order to improve the material functions, the structure and dynamics of the domain homo interface have been clarified for the smooth motion with low friction. Principles for the control of interface structure and lattice softening from the first principle calculations have been established to reduce the friction of motion for the enhancement of higher functionality. Moreover, several multifunctional and high performance new shape change materials have been developed.

    Au-Ti binary and Co added ternary and quaternary alloy systems were used in this study. Several trials were done to fabricate single crystals using OFZ method, but no single crystal was obtained. Probably, some complex phase reactions containing peritectic reaction is related to solidification. Then, instead of single crystal, we used polycrystal alloys for further researches. It was found that Ti-rich offstoichiometric alloys exhibit good mechanical properties, and that aging behavior is not observed in Au-Ti binary alloys but Co-added alloys only. The equilibrium second phase is A15 AuTi3 in the binary system but it is changed to be L12 phase by Co addition. By TEM observations the size of this precipitates is relatively large from sub nm to a few microns, and no clear microstructural change is recognized such as APB and vacancy cluster. Then, the anomalous low temperature aging must be due to the L12 precipitates stabilized by Co addition.

    There is no effective method of microstructural control to suppress the slip deformation that competes with superelastic deformation inβ-Titanium superelastic alloy, though this alloy is a candidate biomedical superelastic alloy. The superelastic deformation in β-titanium alloy is, therefore, not a perfect one ; plastic strain remains after deformation. We propose a new heat-treatment method to precipitate fine α-phase for strengthening that is nucleated at fine ω-phase. The ω-phase brings extreme brittleness and is not used in usual heat-treatment of titanium alloy, whereas it is used as a medium for ω-phase nucleation in our new method. 800MPa in strength and perfect shape recovery are achieved by a three-step heat-treatment : 773K (fine ω precipitation)→1023K (fine α precipitation at ω)→1123K(erasing ω) in Ti-Mo-X (X=Al and Mn). In addition, a low-temperature heat-treatment around 373K as the fourth step improved mechanical property.

    資源的問題のある希土類元素を使用しない強力硬磁石を創製するために、磁歪および磁歪拘束による磁気異方性発現に着目した。微視力学的材料設計-複合材料化により弾性異方性を制御すれば、これにより巨大磁気異方性が発現できる可能性がある。例えば、単純計算からはひずみ量10^<-4>の磁歪拘束ができれば5〜10MJ/m^3程度の磁気異方性エネルギーとなり、これは現在最強の磁石であるNd-Fe-B系磁石と同様の巨大磁気異方性である。この発想を発展させるため、本研究では強磁性元素Ni、磁歪の大きいCoFe204、および、実用上ほぼ最大の磁歪を有するTerfenol-Dを強磁性体として選択し、磁場拘束のための高ヤング率材料としてCu-W一方向繊維強化材を用い、サンドイッチ接合により複合材料を作製し、その磁気特性を振動試料型磁力計で計測すると共に、一次元に楕円体モデルを適応した非線形型磁化曲線および磁気ひずみ曲線の構成方程式を考案し、実際の磁気ひずみとモデル解析とを比較した。特に、Terfenol-Dを用いた場合には無磁化場および飽和磁化場での接合を行った。理論的解析から、磁性体の磁気ひずみ量と磁気ひずみ勾配が複合材料における磁気異方性向上に大きく影響することを見出した。また、Terfenol-Dを用いた複合材料の実験値では計算結果より大きな磁気弾性効果が発現した。飽和磁化状態の時に接合したコンポジットの実験結果と計算結果は一致せず、消磁状態で接合したコンポジットでは計算結果が定性的に一致した。このことから、飽和磁化での接合では実験的な問題があるかあるいは理論式の改善が必要であることが指摘された。および、理論からは、初期に予想した巨大磁気異方性エネルギーの発現は、現存する材料の物性値からは困難であることが示唆されたが、期待より小さいものの複合材料化で磁気異方性は向上できることを示した。

    The purpose of this research is to clarify the relationships among microstructures, defects and mechanical properties of Ni-free biomedical shape memory alloys, especially TiNbAl alloys, through thermo-mechanical treatments to introduce high-energy and high-density lattice defects by severe deformations. In order to enhance their superelastic properties, material strengthening to increase critical stress for slip deformation is effective and this was tried by severe deformations of cold rolling up to 99% in reduction thickness and rapid solidification. Firstly, the formation of texture and superelastic deformation were investigated using Ti-26Nb-3A1 alloy with relatively low martensitic transformation temperatures. It was found that the development of deformation texture is strongly related to true strain and that the texture is rapidly grown after when the true strain becomes over 3. Although the grain size after the solution treatment is coarse around 500μm, the grains become fine and needle-like shape elongated with the rolling direction. Then, the development of recrystallization texture was investigated with various cold rolling reductions. It was found that the development of recrystallization texture is strongly dependent on reduction rate, and that different textures are developed. {001}_β<110>_β type texture is formed when cold rolling reduction is lower than 90%, and further increasing cold rolling reduction, the texture formed is changed to {112}_β<110>_β type. {001}_β<110>_β type exhibits less anisotropy in superelasticity than {112}_β<110>_β, resulting that {001}_β<110>_β type texture is more useful for practical applications. Secondly, the texture formation of α" and α"+β type TiNbA1 alloys was investigated. It was found that deformation and recrystallization textures are {112}_β<110>_β type and {111}_β<110>_β for the α"+β alloy, respectively. Besides, deformation and recrystallization textures of α" alloy are {223}_<α"><302>_<α"> type and {011}_<α"><311>_<α"> for the α" alloy, respectively. Therefore, the type of texture formation as well as superelasticity strongly depends on the type of stable phase in the TiNbAl alloys. Similar results were obtained for the cold rolled wires. Finally, the rapid solidification was done for Ti-24Nb-3A1 but neither texture nor fine grains were formed even though the high energy process of the rapid solidification. It is conclude that texture and superelastic properties of the titanium alloys can be controlled through a proper thermomechanical treatment combined with severe deformation.

    熱処理型アルミニウム合金である2024(Al-4%Cu)および2017(Al-40%Cu-0.5%Mg)を用い,超音波を印加しながら時効熱処理を行い,その時効硬化挙動を超音波印加・無印加で比較した.超音波としては,周波数27KHz,47KHz,100KHz,200KHZ,400KHzおよび1MKHzとし,それぞれ出力は約150Wである.時効処理温度は,2024Alでは100℃〜200℃,2017Alでは0℃〜75℃とした.時効処理は,520℃での溶体化処理後,氷水中に焼きいれ,その後所定の温度で時効処理を行い,ビッカース硬度および電気抵抗を調べた.
    実験の結果,2017Al合金の場合,周波数27KHz,47KHzでは,硬度の時間変化は超音波印加の有無によらなかった.しかし,周波数100KHzでは同じ処理時間では超音波印加処理材の方が硬度が低かった.また,200KHz以上では,超音波印加処理を行った方がより短時間で硬化した.しかし,いずれも十分な時間時効処理を行うと,超音波印加の有無によらず硬度は一定値となった.同様に2024Alを用い周波数200KHzとして超音波印加時効を行った結果,温度100℃および180℃以上の場合には,超音波印加の有無により,時効硬化挙動に顕著な差が見られなかった.しかし,140℃,160℃では超音波印加によりより短時間で硬化し,超音波処理により一定の硬度に達する処理時間は,超音波無しの場合に比べ,最大1/1000に短縮された.しかし,先と同様,十分に処理時間の長い場合の最高硬度は超音波の有無によらなかった.また,電気抵抗についてはその絶対値が小さく,顕著な差が見いだされなかった.以上をまとめ,超音波処理により時効硬化が影響されること,最高硬度は超音波印加の有無によらないこと,超音波により時効が加速または抑制される処理条件があること,が明らかになった.
