Изобретение относитс к области металлургии , и частности к сиособу термической обработки жаропрочных дисперсионно-твердеющнх сп.чавов иа основе никел .The invention relates to the field of metallurgy, and in particular to a method for the heat treatment of heat-resistant dispersion-hardening spheres based on nickel.
Известен способ термической обработки жаропрочных сплавов, включающий нагрев до температуры ковки, ковку, охлаждение на воздухе и старение. Известный способ предусматривает термическую обработку деталей, работаюгцих при температурах до 750°С.The known method of heat treatment of superalloys, including heating to forging temperature, forging, air cooling and aging. The known method provides for heat treatment of parts operating at temperatures up to 750 ° C.
Недостатком известного способа вл етс проведепие закалки после ковки, что не обеспечивает получени высоких механических свойств как при высоких температурах в услови х кратковременной ползучести, так и при комнатной температуре.A disadvantage of the known method is the conduct of quenching after forging, which does not ensure obtaining high mechanical properties both at high temperatures under short-term creep conditions and at room temperature.
Предлагаемый способ отличаетс от известного тем, что после ковки провод т нагрев до температуры начала ковки с выдержкой в течение 3 ч.The proposed method differs from the well-known one in that after forging, the heating is carried out to the temperature of the start of forging with a holding time of 3 hours.
Это обеспечивает повышение механических свойств как при высоких температурах в услови х кратковременной ползучести, так и ири комнатной температуре.This provides an increase in mechanical properties both at high temperatures under short-term creep conditions and at room temperature.
Предлагаемый способ включает следующие операини: нагрев в нагревательной печи при ковочной температуре 1150-1040°С, далее ковку со степеиыо деформации не менее 50% в интервале температур 1150-1040°С. возврат заготовок с температурой 1040-1020 0 в печь The proposed method includes the following operations: heating in a heating furnace at a forging temperature of 1150-1040 ° C, then forging with a strain of at least 50% in the temperature range of 1150-1040 ° C. return of billets with a temperature of 1040-1020 0 to the furnace
с температурой 1150°С, выдержку 3 ч, охлажденпе на воздухе, старение при 950°С 8ч, охлаждение на воздухе.with a temperature of 1150 ° С, exposure 3 h, cooled in air, aging at 950 ° С 8 h, cooling in air.
