| Abstract: | The effects of heat treatment(solution)on phase transformation and properties of TiNi alloy have been studied by means of TEM. Based on the obtained results, the optimum heat treatment has been proposed. The conclusion is∶ when being aging treated at temperature 450-550℃, the alloy of Ti-50.8at%Ni generates much Ti 3Ni 4 phase, and has the highest recovery rate. |

| Keywords: | shape memory alloy aging treatment recovery rate |
