Abstract
In the hardening of magnesium base alloys, especially those containing 7-15 per cent of aluminium, the cast alloy is subjected to solution treatment, hot-worked at 200-500 DEG C. so as substantially to maintain the solid solution produced and then subjected to a precipitation heat treatment. The solution treatment consists in heating to 280-550 DEG C. for not less than 5 hours which may be followed by quenching, and the precipitation treatment at a temperature of 170 DEG C. for a period of 12 hours. In an example an alloy containing 9 per cent of aluminium and 0,2 of manganese is heated at 420 DEG C. for 16 hours, cooled in air, heated to 350 DEG C., extruded and then heated at 170 DEG C. for 12 hours.
