FIELD: metallurgy.
SUBSTANCE: invention can be used at hardiness of storage from alloy АК4-1 or АК4-1p for the following producing the high-precision parts of device. The alloy is heated up to the temperature of hardiness 450°С with the speed 80-120°С per hour and sustained 3 minutes. Then it is made the cooling in the water under the temperature 80-100°С, and then in water under the following temperature 20°С and after it is made the aging.
EFFECT: decrease of the alloy deformation during hardiness and aging.
