摘要
近年来,以Ti-Nb, Ti-Zr, Ti-Ta, Ti-Mo为代表的新型钛基形状记忆合金在航空、航天、医疗和能源等领域展现出重要应用前景,但仍有一些共性的相变问题值得深入探讨。本文对钛基形状记忆合金中的应变马氏体稳定化、马氏体相变的可逆性、应力诱发马氏体相变与超弹性的复杂性和多样性等问题进行了总结和讨论,对深入揭示和理解钛基形状记忆合金的马氏体相变特征及其内在机制,发展高性能合金具有重要参考价值。
In recent years, the new titanium-based shape memory alloys represented by Ti-Nb, Ti-Zr, Ti-Ta and Ti-Mo have shown great application prospects in the fields of aviation, aerospace, medical and energy, there are still some common problems of phase transition worthy of further study. In this paper problems of martensite stabilization induced by strain, reversibility of martensitic transformation, complexity and diversity of martensitic transformation and superelasticity induced by stress in titanium-based shape memory alloys were summarized and discussed. The research results have important reference value for revealing and understanding the characteristics and internal mechanism of martensitic transformation, and developing alloys with good performance.
