I am very honored to receive this award. I greatly appreciate the support of Professor Hideki Hosoda, Professor Tomonari Inamura, all of my collaborators, and laboratory members. Shape memory alloys are functional metallic materials developed in Japan and are used in various applications by taking advantage of their ability to recover their initial shape even when a large strain exceeding the elastic limit is applied. Recently, shape memory alloys have received more and more attention in the field of metal materials. The reason is that the performance of existing Ti-Ni alloys is improving, and the development of new alloys specialized for specific applications such as biomedical, high temperature, and vibration damping is becoming active worldwide. The unique mechanical functionality of shape memory alloys is brought about by a non-diffusional structural phase transformation called the martensitic transformation. In particular, the martensitic transformation induced by external stress plays a central role in the functionality of shape memory alloys; however, its basic understanding is not sufficient. This research aims to establish the basic knowledge by clarifying the stress-induced phase transformation behavior of shape memory alloys by combining various in-situ measurement techniques.
