Paper Abstract

Mechanical tests have been conducted to characterize the shape memory effect and mechanical properties of a NiTi-20 at%Pd high temperature shape memory alloy. The experimental results show that the ratio of the Young's modulus of martensite to austenite is 0.58. The ratio of the yield stress of the martensite to austenite phase is 0.62 and the fully reversible strain is 3%. These values indicate that the shape memory properties of the NiTi-Pd alloys is not as good as those of the NiTi binary alloys. The mechanical properties of the alloy also demonstrate that the ductility of the alloy is significantly lower than that of the NiTi binary alloy. Further studies should be carried out to improve the shape memory effect and enhance the ductility of the alloy.
