ABSTRACT:
The effective transition temperature from martensite to austenite in a dimensionally heat-recoverable memory metal member can be temporarily raised by applying a stress and maintaining the applied stress at a temperature below the raised transition temperature so that the memory metal remains substantially in the martensitic state. When it is desired to utilize the member the stress is removed at a temperature above the original transition temperature. The applied stress is advantageously maintained by a disburdenable keeper. In an especially preferred embodiment the keeper comprises an aluminium tube positioned within a band or tube made from a brass memory alloy, the combined article being suitable as a connector for hydraulic pipes and the like.
