the yield strength of TiNi[11-17]. The hard intermetallic compound Ti2Ni (with microhardness of approximate HV700) is precipitated during the solidification process in both equal-molar and Ti-rich TiNi...-induced reversible martensitic transformation plays an active role in contributing to the wear resistance. The deformation within the pseudoelastic range is recoverable and this rubber-like property......
