Description

Изобретение относитс  к черной металлургии в области обработки сложнолегиро- ванных жаропрочных и жаростойких сплавов на никелевой основе и может быть использ вано во многих отрасл х современной техн ки дл  получени  высокопрочных и долгове ных изделий. Известен способ термомеханической об- , работки дисперси.онно-твердеющих сплавов, включающий закалку с температуры 98О11ОО°С , деформацию с обжатием 4О-7О% и последующий отжиг при 65О-.75О°С. С целью повышени  высокотемпературной ползучести и долговечности предложен способ, отличающийс  от известного тем, что деформацию провод т при температуре отжига в течение 5-12 мин циклично с частотой 0,2-35 кГц при амплитуде дефор мации ниже или равной пределу текучести сплава. Предложенный способ термомеханической обработки включает следующие операции: закалку с темпер атуры- 1О8О-127О°С, циклическую деформацию (сжатие-раст же. ние) при температуре 7ОО°С в течение 5-12 мин с частотой 0,2-35 кГц при амплитуде деформации ниже или равной пределу текучести и последующий отжиг при 65Оь8ОО°С в течение 1-2 час без нагружени . Данный способ позвол ет увеличить долговечность материала при температуре 7ОО°С и напр жении 46 кг/мм в среднем до 8OL.9O час. Пред мет изобретени  1.Способ термомеханической обработки дисперсионно-твердеющих сплавов, включающий закалку, деформацию и отжиг при температуре 65О-75О С в течение 2 час, отличающийс  тем, что, с целью повышени  высокотемпературной ползучести и долговечности, деформацию прово7Д т при температуре отжига в течение 5-12 мин циклично с частотой 0,2-3 5 кГц при амплитуде деформации ниже или равной пределу те1сучести. 2.Способ по п. 1,отличающийс   тем, что закалку провод т с темпе- paryp,Jk 1080-1270°С.The invention relates to ferrous metallurgy in the field of processing complex-alloyed heat-resistant and heat-resistant nickel-based alloys and can be used in many areas of modern technology to produce high-strength and long-lasting products. The known method of thermomechanical processing, treatment of dispersion-hardening alloys, including quenching from a temperature of 98 ° 11 ° C, deformation with compression of 10-7.0% and subsequent annealing at 65 ° -75 ° C. In order to increase the high-temperature creep and durability, a method is proposed that differs from the known fact that the deformation is carried out at an annealing temperature for 5-12 min cyclically at a frequency of 0.2-35 kHz with a strain amplitude lower than or equal to the yield strength of the alloy. The proposed method of thermomechanical processing includes the following operations: hardening at a temperature of –O8O-127O ° C, cyclic deformation (compression-stretching the same) at a temperature of 7OO ° C for 5–12 min with a frequency of 0.2–35 kHz with amplitude deformations less than or equal to the yield strength and subsequent annealing at 65 ° -8 ° C for 1-2 hours without loading. This method allows to increase the durability of the material at a temperature of 7OO ° C and a voltage of 46 kg / mm on average up to 8OL.9O hour. 1. Method of thermomechanical treatment of dispersion-hardening alloys, including quenching, deformation and annealing at a temperature of 65 ° -75 ° C for 2 hours, characterized in that, in order to increase the high-temperature creep and durability, the deformation takes place at annealing temperature for 5–12 min cyclically with a frequency of 0.2–3.5 kHz with a strain amplitude lower than or equal to the thermal limit. 2. A method according to claim 1, characterized in that the quenching is carried out at a temperature of Jp 1080-1270 ° C.
