A shape-memory alloy (SMA) is a type of metallic alloy that can "remember" its original, pre-deformed shape. When an SMA is subjected to a specific temperature range, it can undergo a phase transformation that allows it to return to its original shape after being deformed. This unique property is often referred to as the "shape-memory effect.
