| Outline of Final Research Achievements |
This research developed two kinds of high functional shape memory alloys, which are a functionally graded and a high corrosion resistance TiNi alloys, in order to expand applications of the TiNi shape memory alloy into medical and industrial fields. The researcher revealed that the functionally graded TiNi shape memory alloy shows a gradual change of local strain distributions by appropriate thermomechanical treatment to the sintered compact having several Ni concentrations along its axial direction. The researchers also revealed that the TiNi alloy which has a thin passive layer generated by a thermal nitridation treatment shows a high corrosion resistance compare to that of the untreated TiNi shape memory alloy.
