Abstract
In this research, the fabrication conditions of Ni-rich Ti-55at%Ni alloy by pulse-current sintering and the shape memory properties of the sintered alloy were investigated experimentally. The sintering was performed at various temperatures in a vacuum, and then the solution treatment was carried out at various temperatures in Ar gas atmosphere. Finally the aging treatment was performed to improve the shape memory properties of the alloy. As a result, the optimum sintering and solution treatment conditions could be obtained. It was also found that the alloy shows shape memory properties by performing aging treatment and the deformation resistance and recovery strain depend on the microstructure of the aged alloy.
