Abstract: Phase transformation behaviors, shape memory effects and mechanical properties of TiNiMo shape memory alloys are investigated. It is found that a R phase transformation exists in TiNiMo alloy, and the adition of Mo will lower the martensite start (Ms) temperature of TiNi alloy, and that the Ms temperatures of Ti(50)Ni(48.5),Mo(1.5 )and Ti(50)Ni(48)Mo(2.0 )alloys are -85℃ and -103℃, respectively. The two alloys will gain 8.06% and 7.71% shape memory effects under 8.51% and 8.26% pre-strain,...
