| Outline of Final Research Achievements |
Superelasticity in shape memory alloy shows a large elastic strain due to martensitic transformation. This project was a basic research to apply the first ferrous superelastic alloys to large structural components. The following studies were conducted in Fe-Ni-Co-Al-based and Fe-Mn-Al-Ni-based alloy systems: (i) suppression of grain boundary precipitates, (ii) control of fine coherent precipitates, (iii) control of grain growth and superelasticity, (iv) evaluation of materials properties and possibilities of practical application.
