研究了Sn含量和时效条件对Ti-Mo-Sn合金超弹性的影响。马氏体相变温度随Sn含量的增加而降低。固溶处理后的Ti-5mol%Mo-5mol%Sn合金在拉伸试验中获得了3.0%的超弹性应变。Ti-5 mol%Mo-5 mol%Sn合金在室温下的超弹性通过在873 K下时效180 ~ 420 s得到改善。在873 K下时效300 s的试样在拉伸试验中表现出超弹性，回复应变为3.5%。在循环拉伸变形中，始终实现3.0%的恢复应变。
The effects of Sn content and aging conditions on superelasticity in Ti-Mo-Sn alloys were investigated. Martensitic transformation temperature decreased with an increasing of Sn content. A large superelastic strain of 3.0% was obtained in a solution-treated Ti-5 mol%Mo-5 mol%Sn alloy in the tensile test. The superelasticity in the Ti-5 mol%Mo-5 mol%Sn at room temperature was improved by aging at 873 K for short periods between 180 and 420 s. A specimen aged at 873 K for 300 s exhibited superelasticity with a recovery strain of 3.5% in the tensile test. A recovery strain of 3.0% was consistently achieved in cyclic tensile deformations.
