What are nitinol and SMA?

Shape memory alloys (SMA) are alloys with "Memory": They can return to their original shape after being deformed via a change in pressure or temperature. SMA are used in a wide variety of applications - including metallurgy, manufacturing, biomedicine, and children's arts and crafts. The shape memory alloy is a material that goes through a stage change when it encounters a mechanical pressure or temperature change. At the point when the conditions recover to business as usual, the SMA "remembers" its original shape and reverts to it. Nitinol Shape Memory Alloys undergo a phase transformation in their crystal structure when cooled from the stronger, high temperature from (Austenite) to the weaker, low temperature from  (Martensite). This inherent phase transformation is the basis for the unique properties of these alloys in particular, Shape Memory and Superelasticity.

Superelastic Effect

An elastic (reversible) responses to an applied temperature, caused by a phase transformation between the austenitic and martensitic phases of a crystal.

Ms- Initial temperature for austenite to martensite transition

Mf- Final temperature for austenite to martensite transition

As- Initial temperature for martensite to austenite transition

Af- Final temperature for martensite to austenite transition

Shape Memory Effect

"Shape Memory Alloy" SMA describes the restoration of the original shape of a plastically deformed sample upon heating.
