Shape Memory Alloys

In metallurgy, a shape-memory alloy (SMA) is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated. It may also be called memory metal, memory alloy, smart metal, smart alloy, or muscle wire. Parts made of shape-memory alloys can be lightweight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based systems. They can also be used to make hermetic … WebJun 4, 2024 · A shape memory alloy is, in essence, a combination of metals that has the ability to return to a certain shape if the temperature is conducive to it doing so.
