What does shape memory alloy mean?

A shape-memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that "remembers" its original shape and that when deformed returns to its pre-deformed shape when heated. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems.See all results for this questionWhat does metal have a shape memory?A shape-memory alloy is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated.

How do shape memory alloys (SMA) work?

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
