Abstract

A machine for the thermo-mechanical treatment of parts made of memory alloys contains: a thermally insulated chamber connected to a source of gaseous fluid and a support, capable of being introduced into a chamber, for carrying a plurality of crowns superimposed on one another. The parts made of memory alloy are placed between the crowns where the gaseous fluid passes through. Tension is applied to the crown in a controlled operating cycle.
