Recent progress in shape memory alloys

Abstract

In this paper, the progress on shape memory alloys (SMAs) for the past 10 years was reviewed and research trends in the field were briefly introduced. Especially, basic properties in some novel alloys, such as the ductile Cu-Al-Mn SMA, ferrous superelastic alloys and Ni-Mn-based metamagnetic SMAs are focused on and the superelastic behavior at cryogenic temperatures in some SMAs, such as TiNi and Ni-Co-Mn-In alloys, was introduced.
