A research group led by Assistant Professor Toshihiro Omori, Professor KAINUMA Ryosuke and Professor Emeritus Ishida Kiyohito at Graduate School of Engineering, Tohoku University has successfully developed superelastic ferrous alloys (shape memory alloys) which show a very small temperature dependence.

 Fe-Mn-Al-Ni alloys, developed in this study, shows a very small temperature dependence of the superelastic stress and available over a temperature range from -200℃ to 150℃. The alloys are expected to be applied to industrial products, such as automobile components and space materials. Since they are cheap and easy to fabricate, they also will be applied to large members like earthquake-resistant members.
