Abstract
Shape memory alloy (SMA) is one of actuator materials which converts thermal energy into mechanical energy. Since it has much larger output strain and stress compared to piezoelectric materials or magnetostrictive materials. Thus SMA is suitable as actuator materials for extreme environment and in the areas which require a large motion and high energy density. The purpose of present study is to develop the shape memory alloys which can operate at temperatures below liquid nitrogen temperature. Effect of grain size and chemical composition on martensitic transformation were assessed in TiNi and Cu-Al-Mn alloys.
