Shape Memory Alloys

Shape Memory Alloys (often called ‘memory metals’) are a class of metal alloys that "remember" their original shape. When the metals are bent or twisted from their original shape, they can retain their initial form when heated to a certain temperature.

Materials Science and Engineering influences most industries, and many companies are developing applications for shape memory alloys.
