FIELD: metallurgy.
SUBSTANCE: method of heat treatment of parts made of heat-resistant nickel alloys includes heating at a temperature of 5-25°C above the solvus temperature with soaking time of 3-4 hours, cooling after heating at a rate higher than 20°C/min, and subsequent aging in three stages: stage 1 - 910°C, soaking time 3:00, stage 2 - 750°C, soaking time 8 hours and stage 3- 700°C, soaking time 17 hours.
EFFECT: increased life and reliability of parts operating under conditions of rigid loading while reducing their weight.
