Shape memory alloy (SMA) is a class of Smart Materials that can exhibit unique thermomechanical phenomena (Shape memory effect and superelasticity/pseudo-elasticity), which involve the restoration (remembrance) of the SMAs original shape after being excessively deformed.Shape Memory Alloys Research Papers - Academia.eduShape Memory Alloys (SMAs) constitute a class of materials that present highly non-linear, thermo-mechanically coupled behaviour that is related with the phenomena accompanying the diffusionless, solid-state phase transformation.Shape Memory Alloys - University of AlbertaIn most shape memory alloys, a temperature change of only about 10°C is necessary to initiate this phase change. The two phases, which occur in shape memory alloys, are Martensite, and Austenite. Martensite, is the relatively soft and easily deformed phase of shape memory alloys, which exists at lower temperatures.
A Shape Memory Alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that remembers its original, cold-forged shape: returning the pre-deformed shape by heating.

When a SMA is in martensite form at lower temperatures, the metal can easily be deformed into any shape. When the alloy is heated, it goes through transformation from martensite to austenite. In the austenite phase, the memory metal "remembers" the shape it had before it was deformed.See all results for this questionHow Shape Memory Alloys work - University of Washington14 rows · Shape memory alloys display two distinct crystal structures or phases.

As heat is a property that changes and determines the shape of a metal, there are alloys that use this property at certain temperatures to remember their shapes (crystal structure). When they are deformed and heated, they are capable of retracing their parental crystal structure. ThiSee more on geekswipe.netPublished: Dec 31, 2014
