Austenite — (or gamma phase iron) is a metallic non magnetic solid solution of iron and an alloying element. In plain carbon steel, austenite exists above the critical eutectoid temperature of 1000 K (about 727 °C); other alloys of steel have different… … Wikipedia
Shape memory alloy — A shape memory alloy (SMA, also known as a smart alloy, memory metal, or muscle wire) is an alloy that remembers its shape, and can be returned to that shape after being deformed, by applying heat to the alloy. When the shape memory effect is… … Wikipedia

Cryogenic hardening — is a cryogenic heat treating process where the material is cooled to approximately −185 °C (−301 °F), usually using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels, provided their composition and … Wikipedia
Pseudoelasticity — Pseudoelasticity, or sometimes called superelasticity, is an elastic (impermanent) response to relatively high stress caused by a phase transformation between the austenitic and martensitic phases of a crystal. It is exhibited in Shape memory… … Wikipedia
