摘　　要：1.Introduction Ti-Ni-Hf high temperature shape memory alloys have attracted great interests of many researchers due to the higher transformation temperatures and relatively lower cost[1,2].However,the recoverable strain is about 3%,which is signifcantly lower than the theoretical value[3-5].The functional performances of shape memory alloys are closely related to the substructure of twinned martensite and the structure of intervariant interface.
