Reversibility of the martensitic transformations and shape-memory effects

Abstract

The results of the investigations of main peculiarities and reversibility of the martensitic transformations in different materials are considered and discussed. Unusual mechanical properties such as shape-memory effect, superelasticity, superplasticity, and other phenomena caused by these transitions are also analysed. The values of the recovering deformation are determined by the mechanism of the martensitic transformations and their reversibility. Reasons for their differences for the alloys with different characters of the martensitic transitions are also discussed.
