Abstract
A method for the low temperature heat treatment of an age-hardenable magnesium based alloy, including following steps: (a) providing a solution heat-treated and quenched age-hardenable magnesium based alloy; and (b) subjecting said alloy to low temperature ageing below 120° C. for a period of time sufficient to develop an enhanced ageing response.

A method for the low temperature heat treatment of an age-hardenable magnesium-based alloy, including the steps:
- (a) providing a solution heat-treated and quenched age-hardenable magnesium based alloy;
- and
- (b) subjecting said alloy to low temperature ageing below 120° C. for a period of time sufficient to develop an enhanced ageing response.
A method for producing an age-hardenable magnesium-based alloy, including the steps:
- (a) solution treating, within a suitable elevated temperature range or ranges, an age-hardenable magnesium based alloy for a time or times sufficient to allow the elements active in the precipitation reaction to be dissolved into solid solution;
- (b) quenching the solution treated alloy from the temperature cycle for step (a) whereby the dissolved elements are retained in a supersaturated solid solution;
- and
- (c) subjecting the quenched alloy from step (b) to low temperature ageing below 120° C. for a period of time sufficient to develop an enhanced ageing response.
