钛基形状记忆合金的马氏体相变问题研究

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.
