Abstract

The effects of Pd content on microstructures, martensitic transformation of Ti_50.5Ni_38-xCu_11.5Pd_x (x = 3, 4, 4.5, 5.5) alloys have been investigated. There all show orthogonal B19 martensite in the Ti_50.5Ni_38-xCu_11.5Pd_x alloys. The doping of Pd decreases thermal hysteresis remarkably, approaching to the minimum (1.7 °C) at the Pd content of 4.5 at.%. Meanwhile, the thermal stability is dramatically improved with Pd doping, with a change of less than 1 °C in transformation temperature after 100 thermal cycles.
