Shape memory alloy smart material
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 … Webb[13, 14] In the case of metals, shape memory alloys (SMAs) are of particular interest due to the large strains these materials can withstand. They have been investigated as …
