Abstract
In this work, Ti-Ni shape memory alloy thin films were irradiated by 1.7Â MeV electron with three types of fluences: 4Â ÃÂ 1020, 7Â ÃÂ 1020 and 1Â ÃÂ 1021/m2. The influence of electron irradiation on the transformation behavior of the TiNi thin films were investigated by differential scanning calorimetry. The transformation temperatures As and Af shifted to higher temperature after electron irradiation, the martensite was stabilized. The electron irradiation effect can be easily eliminated by one thermal cycle. The shifts of the transformation temperatures can be explained from the change of potential energy barrier and coherency energy between parent phase and martensite after irradiation.
