Изобретение относитс  к металлургии , в частности к термической обработке жаропрочных сплавов на основе никел .This invention relates to metallurgy, in particular to the heat treatment of nickel-based superalloys.

Известен способ термической обработки жаропрочных сплавов на основе никел , включающий нагрев до температуры на 100-200 0 выше температуры рекристаллизации, выдержку при этой температуре, деформацию и охлаждение на воздухе.The known method of heat treatment of superalloys based on nickel, including heating to a temperature of 100-200 0 above the recrystallization temperature, holding at this temperature, deformation and air cooling.

Дл  повышени  технологической пластичности при комнатной температуре по предложенному способу выдержку провод т в течение 2-20 час, охлаждение со скоростью 100-50 С/ /мин, а деформацию осуществл ют при комнатной температуре после охлаждени .To increase technological plasticity at room temperature, according to the proposed method, the exposure is carried out for 2-20 hours, cooled at a rate of 100-50 C / min, and deformation is carried out at room temperature after cooling.

Заготовку нагревают до температуры , превышающей на 100-200OQ температуру начала рекристаллизации , выдерживают при этой температуре 2-20 час, затем охлаждают со скоростью 100-50 0/мин. Далее за-т готовку деформируют вхолодную соThe billet is heated to a temperature exceeding by 100-200 OQ the temperature of the beginning of recrystallization, kept at this temperature for 2-20 hours, then cooled at a speed of 100-50 0 / min. Further, over-deform the cooking in cold

степенью деформации до 75.the degree of deformation to 75.

Сплавы на основе никел , обработанные по предложенному способу, имеют следующие свойства: Предел прочности,кг/мм2 lOf-IOe Предел текучести,кг/мм2 6,5-72,.Nickel-based alloys, treated according to the proposed method, have the following properties: Strength, kg / mm2 lOf-IOe Yield strength, kg / mm2 6.5-72 ,.
