WebbRT @Rainmaker1973: A shape-memory alloy (SMA) is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated. WebbShape memory alloys (SMA) constitute a group of metallic materials with the ability to recover a previously defined length or a shape when subjected to an appropriate thermomechanical load (1). When there is a limitation of shape recovery, these alloys promote high restitution forces.
