Abstract

The influence of the thermal cycling training under constant strain on the two-way shape memory effect (TWSME) in a Ti36Ni49Hf15 high temperature shape memory alloy (SMA) has been investigated by bending tests. The results indicate that the training procedure is beneficial to get the better TWSME. The two-way shape memory strain increases with the increase of the training strain and decreases with the increase of the training temperature. The TWSME obtained in the present alloy shows poorer stability than that obtained in the TiNi alloys.
