  additional third elements of Cr and Mn clearly showed shape memory effect. On the other hand, when the additional third elements were V, Cr, Mn, and Mo, the ternary alloys performed slight pseudoelasticity or limited superelasticity while there was no superelasticity observed as the third elements were Fe and Co. According to the investigation of fundamental mechanical properties, the additional third elements

  摘要 形状记忆合金 (SMA) 是急需的生物材料和医学应用问题中的重要课题。本研究系统地研究了一系列有前景的近共析 Ti-4 at.% Au-5 at.% X（X = 3d 过渡金属：V、Cr、Mn、Fe、Co、Ni 和 Cu）合金。试样采用物理冶金法制备，并通过XRD、弯曲试验、维氏硬度和拉伸试验进行分析。Cr和Mn的附加第三种元素清楚地表现出形状记忆效应。另一方面，当添加的第三种元素为 V、Cr、Mn 和 Mo 时，三元合金表现出轻微的伪弹性或有限的超弹性，而由于第三种元素是 Fe 和 Co，因此没有观察到超弹性。力学性能，附加的第三种元素 Cr 和 Mn，被归类为优化组，基于其强度、延展性、形状记忆效应和超弹性效应的评估优于其他合金。本研究系统地筛选了 3d 过渡金属对近共析 Ti-4 at.% Au-5 at.% X 合金的影响。结果可以作为数据库和指南，用于进一步的标本制备和未来研究的调查。

  Two intermetallic compounds, HfPd and TiAu have been analyzed as potential high temperature shape memory alloys. In spite of a reversible martensitic transformation detected at high temperature in HfPd, no meaningful shape recovery has been observed in this compound by TMA after compression pre-strain of the martensite.The mechanical properties of TiAu at high temperatures have been evaluated by thermal cycling under compression load and by compression tests. A high mobility of the dislocations is found around martensitic transformation temperatures, which limits the functional properties of this high temperature shape memory alloy. Some improvement should be obtained by precipitation hardening. (C) 2012 Elsevier B.V. All rights reserved.

  Ti-based alloys containing Pd, Au, and Nb were produced by tilt-casting and subsequently dual-axially forged at elevated temperatures. It is shown that the mechanical properties, electrochemical behavior and biocompatibility of the studied alloys are close to, or even better, than those of typical commercial Ti-based low-alloys widely used as biological implants. This demonstrates that the Ti94Pd3Au3, Ti94Pd3Nb3 and Ti94Pd6 alloys showed a good potential for application as biomaterials. (C) 2017 Elsevier B.V. All rights reserved.
• Electronic structure and stability of Ti-based<i>B</i>2 shape-memory compounds: X-ray and ultraviolet photoelectron spectra

  The evolution of x-ray photoelectron and ultraviolet spectra and their modification at the phase transformation B2-B19(B19') of equiatomic TiM and quasibinary Ti(Ni,M) compounds, where M stands for Fe, Co, Ni, Pd, Pt, Au, and Cu, are presented. Investigation of x-ray photoemission spectroscopy includes valence bands, satellites, and core-level energy studies. As the atomic number of M increases (both within the same period and along the group), its d states become more localized, the maximum and the center of gravity of the d bands shift towards the bottom of the valence band, and the M contribution to the density of states (DOS) at the Fermi level, N(E(F)), degrades. The DOS localization is accompanied by a spatial localization of the M d electrons resulting in weakening of the d-d covalent bonds between the alloy components and, thus, destabilizing the B2 phase. While the contribution of M d electrons to the DOS at E(F) decreases, the Ti d electron portion increases to such an extent that, e.g., in TiPd and TiAu, the M contribution to N(E(F)) is almost negligible. The increase in core-level energy of all partners in compounds with respect to the elemental state is discussed in terms of covalency. The M d band localization leads to an increase of many-body interactions and, as a consequence, we managed to observe the Pd satellites without resonance enhancement. The B2-B19' phase transition is accompanied by modification of the DOS which affects the Ti d states in general. Having analyzed the electronic structure we introduce parameters controlling the B2 phase stability and suggest a phenomenological formula for the martensitic-transformation temperature which satisfactorily describes the experimental behavior.
