Two-way shape memory effect by the cyclic bending

Abstract

A shape memory alloy has various interesting characteristics. One of them is the so-called two-way shape memory effect which remembers both of shapes of the low and high temperature sides. Training is a way to give the two-way shape memory effect to SMA. In this research, the cyclic bending was applied to Ni-Ti shape memory alloy wire, and the two-way shape memory effect was observed and discussed.
