| Abstract Scope |
In 2016, we found and reported a Mg-20.5 at.% Sc alloy shows superelasticity. The working temperature was, however, too low (-150ºC) for the alloy to be put into practical use. Since the phase stability of the matrix bcc phase and the martensite phase largely depends on Sc content, we controlled it and recently realized superelasticity even at room temperature in a Mg-18.8 at.% Sc alloy. The obtained superelastic strain was, however, just 0.7% which is much smaller than that in practical superelastic alloy, Ni-Ti (6-8%). In my presentation, I will present our recent work especially on the effect of aging heat treatment on martensitic transformation and room temperature superelasticity in Mg-Sc alloy. |
