Memory metal. Second in a series of three images showing samples of a memory metal regaining their original shape under heat. Memory metals are alloys of nickel, titanium & aluminium or copper. Once manufactured in a certain shape (here an 'S'), they may be deformed with little effort, but regain their shape upon gentle heating. This property depends on the atomic structure of the alloy; with gentle heat the alloy becomes plastic and is able to re-arrange the relative positions of its atoms to the minimum energy structure in which it was manufactured. Compare with T742/024 and T742/026.
