Webb28 sep. 2001 · Engineering Titanium-nickel (TiNi) based shape memory alloys (SMAs) are used in a wide range of applications. They are especially practical as thin film actuators because of the large work output per unit of actuator mass and ability for rapid thermal cycling due to large surface to volume ratio. Webbshape-memory alloy (SMA,memory metal, smart alloy) is an alloy that "remembers" its original shape and that when deformed returns to its pre-deformed shape when heated. NiTi's shape memory and superelastic characteristics are unique to shape memory alloys and create an opportunity for innovation in a variety of industries.
