Abstract:TiNi60 alloy was considered as a new type of superelastic bearing material with excellent properties of low elasticity modulus, high hardness, high specific strength, non-magnetism, good dimensional stability and strong corrosion resistance. It was deeply investigated by NASA and other foreign research institutes. The characteristics of TiNi60 alloy were systematically described, the latest research progress in smelting and processing, hardness strengthening mechanism, mechanical properties, tribological properties, high temperature oxidation resistance and superelasticity were discussed, and some problems in current research were analyzed. Moreover, the application prospects in aerospace and research direction of TiNi60 alloy were discussed in order to promote the development of related research.
