FIELD: plastic metal working.
SUBSTANCE: invention can be used in metallurgy and aircraft industry at manufacture of important parts, mainly, parts of gas-turbine engines. According to proposed method, blank is subjected to cross upsetting to form plate. Then plate is installed in flat dies with provision of vertical direction of plate material fiber and is subjected to spinning to form disk. After spinning, blank is turned over, its end surfaces are leveled, blank is broached and rolled to final sizes.
EFFECT: improved physical and mechanical properties of article in direction of action of maximum loads in operation.
