FIELD: metallurgy. SUBSTANCE: method for enhancing cyclic strength of gas turbine engine of refractory nickel base alloy comprises steps of heating part until temperature more than 600 C but lower than temperature of phase transitions and subsequent intensive cooling of heated part at rate of heat removal providing heat emission factor α no less than (1.5x10 - 2.5x10)104 Wt/sq. m C. Cooling may be realized at use of pressurized liquid whose pressure corresponds to 5-6 At. EFFECT: enhanced fatigue characteristics of gas turbine engines. 3 cl, 2 dwg, 4 ex
