Description
Изобретение относитс к обработке металлов давлением, а именно к штамповке деталей из жаропрочных сплавов на никелевой основе.The invention relates to the processing of metals by pressure, in particular to the stamping of parts from high-temperature nickel-based alloys.
Известен способ изготовлени поковок из жаропрочных сплавов на никелевой основе, содержащий операции гор чей осадки, штамповки и объемного полугор чего наклепа, . устран ющего разнозернистость материала поковки. Однако при этом способе из-за недостатка требуемой мощности оборудовани при изготовлении крупногабаритных поковок не подавл етс как наследственна , так и деформационна структура неоднородности материала щтампуемого издели .A known method of manufacturing forgings from heat-resistant nickel-based alloys, containing the operations of hot slump, punching and a bulk half-hem, of which work hardening,. eliminating the material granularity of the forging material. However, with this method, due to the lack of the required equipment power in the manufacture of large-sized forgings, neither the hereditary nor the deformation structure of the heterogeneity of the material of the product being molded is suppressed.
Предлагаемый способ отличаетс от известного тем, что объемный наклеп осуществл ют в процессе гор чей осадки заготовки, которую производ т при 800-1050° С со степенью деформации 15-60%.The proposed method differs from the known one in that the volume hardening is carried out in the process of hot draft precipitation, which is produced at 800-1050 ° C with a degree of deformation of 15-60%.
Это сокращает технологический цикл и устран ет разнозернистость материала крупногабаритных поковок.This reduces the production cycle and eliminates the heterogeneous grain of material of large-sized forgings.
Сущность предлагаемого способа заключаетс в том, что исходную заготовку из жаропрочного сплава на никелевой основе на первой операции в процессе осадки на «шайбу-The essence of the proposed method lies in the fact that the original billet of a heat-resistant nickel-based alloy in the first operation in the process of precipitation on a "puck
подвергают объемному полугор чему наклепу . При этом заготовку нагревают до 800- 1050° С и осаживают со степенью деформации 15-60%. Затем полученную шайбу нагревают до 980-1150 С и штампуют. После этого осуществл ют термическую обработку по обычному релчпму дл сплавов на никелевой основе. Шайбы, изготовленные предлагаемым способом , пмеют однородную мелкозернистую структуру (величпна зерна в пределах 4-5 баллов). Така структура позвол ет гарантировать достаточно высокий уровень механических свойств продукции.subjected to volumetric polugor something to pep. In this case, the billet is heated to 800-1050 ° C and precipitated with a degree of deformation of 15-60%. Then, the resulting washer is heated to 980-1150 ° C and stamped. Thereafter, heat treatment is carried out according to the usual solution for nickel base alloys. The washers made by the proposed method have a homogeneous fine-grained structure (the grain size is within 4-5 points). Such a structure ensures a sufficiently high level of mechanical properties of the product.
