Superelastic property induced by low-temperature heating of a shape memory Ti–24Nb–0.5Si biomedical alloy

Abstract : In this study, we have explored a new way to obtain a superelastic titanium-based alloy. Contrary to the classical method consisting to obtain the β microstructure directly by water quenching from the high temperature β-phase domain, this way consists in obtaining first a shape memory alloy displaying a fully α'' martensitic microstructure and then a superelastic behavior after applying a low temperature heating.
