A research group led by Assistant Professor Toshihiro Omori, Postdoctoral Fellow Yuki Tanaka at Graduate School of Engineering, Tohoku University and Professor Ryosuke Kainuma at Institute of Multidisciplinary Research for Advanced Materials, Tohoku University has successfully developed ferrous high-strength, shape-memory alloy exhibiting an superelastic strain of 10 to 13%, just like rubber.

 The research group has first developed ferrous polycrystalline bulk alloy showing superelasticity at room temperature by element additions and thermomechanical treatment. Titanium is replaced by aluminum in ferrous shape-memory alloy (Fe-Ni-Co-Ti) on which the group have studied.

 The research has been conducted as part of New Energy and Industrial Technology Development Organization (NEDO) Grant Program. The research results have been published in “Science” by American Association for the Advancement of Science (AAAS). The paper’s title is “Ferrous
Polycrystalline Shape-Memory Alloy Showing Huge Superelasticity.”
