Abstract

A bath for the heat-treatment of light alloys containing magnesium at temperatures exceeding 275 DEG C. consists of fused anhydrous sodium bichromate and/or fused anhydrous potassium bichromate. When both bichromates are used, the bath consists of 3 parts of sodium bichromate and 1 part of potassium bichromate. In an example, a magnesium alloy containing 8,5 per cent of aluminium and 0,3 of manganese was heated in a bath consisting of 3 parts of fused anhydrous sodium bichromate and 1 part of fused anhydrous potassium bichromate at a temperature of 420 DEG C., quenched and then heated for 2 hours in an annealing furnace at a temperature of 180 DEG C.
