Title: Materials science: Alloys with long memories.
Authors: Omori, Toshihiro1, Kainuma, Ryosuke1
Source: Nature. 10/3/2013, Vol. 502 Issue 7469, p42-44. 3p.
Subjects: Shape memory alloys, Alloys, Effect of temperature on alloys, Critical temperature, Phase equilibrium
Abstract: The article focuses on a research that reflects on the development of shape-memory alloys that undergoes reproducible phase transition and can also develop materials that remember their shape after deformation. It informs that a plastic strain introduced at low temperatures in shape-memory alloys can perfectly reversed when the material is heated above a critical temperature. It states taht shape-memory and superelastic prop­erties are associated with a solid-to-solid phase transition.
