Influence of Thermal Cycling on Dilatation and Electrical Resistance of Ti-49.8 at.%Ni Alloy After Hot Rolling

摘要：

The effect of thermal cycling of the Ti -49.8 at. % Ni alloy deformed by rolling at 500 ℃ on dilatation of the material was investigated. It was shown that R → B2 and B19→ B2 phase transformations take place during heating due to retaining of R-phase at the lowest temperature of cycling. The evolution and subsequent stabilization of two-way shape memory effect (TWSME) upon thermal cycling are caused by decreasing of the residual B19-martensitic phase formed during rolling. It was revealed that recoverable strain of the alloy doesnt exceed 0.8 % even after forty cycles.
