摘　　要：不同于传统钛基形状记忆合金,Ti-Zr合金中Ti与Zr可实现无限固溶,其强度高于纯Ti和纯Zr,且生物毒性远小于Ti-Ni基合金,可作为植入体用于生物医学等领域。另外,通过成型工艺优化和合金化,可改善Ti-Zr基形状记忆合金的力学性能,用于高温等极端环境。然而,熔炼较难和形状恢复率不足等问题,对Ti-Zr基合金的发展提出了考验。为此,本文介绍了Ti-Zr基形状记忆合金的研究进展,重点阐述了其相变特性、显微组织、形状记忆效应与力学性能,同时指出了目前存在的问题,展望了未来发展方向。Unlike traditional titanium based shape memory alloys,Ti-Zr alloy can achieve infinite solid solution of Ti and Zr,with higher strength than pure Ti and Zr,and much lower biological toxicity than Ti-Ni based alloys.It can be used as an implant in biomedical and other fields.In addition,by optimizing the forming process and alloying,the mechanical properties of the Ti-Zr based shape memory alloys can be improved for use in extreme environments such as high temperatures.However,difficulties in melting and insufficient shape recovery rate pose challenges to the development of the Ti-Zr based alloys.Therefore,this article introduces the research progress of the Ti-Zr based shape memory alloys,focusing on their phase transformation characteristics,microstructure,shape memory effect and mechanical properties.At the same time,it points out the current problems and looks forward to future development directions.
