Shape Memory Alloys

Annual Review of Materials Science, 1988
In some alloys, a given plastic strain recovers completely when the con­ cerned alloy is heated above a certain temperature. This phenomenon, shape memory effect (SME), was observed in Au-Cd (1) and In-Tl (2) alloys in the first half of 1950s. However, SME was not a focus of research until it was found in a Ti-Ni alloy (3) in 1963, when the phenomenon ...
