摘　　要：综述了近年来在TiNi基形状记忆合金中添加的合金元素种类,以及各种合金元素对TiNi基形状记忆合金性能的影响。分析了加入Cu、Cr、Ce、Hf、Pd、Co和Al合金元素对材料相变、形状记忆效应和超弹性的影响,提出了该研究领域今后的研究重点和需进一步解决的问题。Alloying elements types added in TiNi-based shape memory alloys recently and the effect of alloying elements on the properties of Ti Ni-based shape memory alloys were reviewed. The effects of the alloying elements Cu, Cr, Ce, Hf,Pd, Co and Al on the phase transformation, shape memory effects and superelasticity of the alloy were analyzed. The research emphasis in the future and the problems need to be further solved in this field are put forward.
