ABSTRACT:
A method of making a heat-recoverable article which comprises cooling an article in a first shape from a first temperature to a lower temperature, said article being formed from an alloy comprising at least one phase in the form of a primary solid solution of a first metal with at least one other metallic element, which solution on cooling from said first temperature either (1) at least partially transforms into an essentially bonded martensite or (2) retains the high temperature phase but which transforms to an essentially bonded martensite on cold working, and then deforming the article into a second shape, the temperature and rate of cooling being such that, on reheating, the article at least partly resumes the first shape.
