Numerous metallic alloys are now known to exhibit a shape memory effect through which an article deformed at a lower temperature will regain its original undeformed shape when heated to a higher temperature. This behavior is basically a consequence of a martensitic phase transformation.

Abstract The term shape memory alloys (SMAs) refers to the group of metallic materials that demonstrate the ability to return to some previously defined shape or size when subjected to the appropriate thermal procedure. Materials that exhibit shape memory only upon heating are referred to as having a one-way shape memory.

Shape memory is the ability of a material to remember its original shape, either after mechanical deformation (one-way effect) or by cooling and heating (two-way effect). This phenonemon is based on a structural phase transformation, which is diffusionless and connected with large amounts of homogeneous shear. It is known as martensitic transformation.

Shape memory alloys are mixtures of many martensites and of austenite. The composition of the mixture varies: the matensites and the austenite transform into one another. These phase changes can be produced either by thermal actions or by mechanical actions.
