FIELD: metallurgy; heat treatment of castings made from AK8M alloy.
SUBSTANCE: proposed method consists in annealing the castings made on base of AK8M aluminum and hardened by heat treatment. Castings are heated at temperature of 420-450C and are held at heat for two hours, after which they are cooled down in air.
EFFECT: enhanced ductility and reliability; improved quality of castings; possibility of dressing the castings without cracking.
