Shape memory alloys have the ability to recover from deformation due to the thermoelastic martensitic phase transformation that occurs inside the material during deformation. There are two phases in shape memory alloys: high temperature phase austenite phase and low temperature phase martensite phase. The shape memory alloy spring is defined as the temperature rises, the spring shrinks back to the memory shape, and the temperature drops, the spring elongates back to the memory shape.
