FIELD: metallurgy.
SUBSTANCE: there is proposed method for obtaining irregular-shaped discs from high-resistant nickel alloys, which includes vacuum-induction melting, production of workpiece, homogenising annealing in 7 steps, heating for deformation in 2 steps, deformation and heat treatment. The items obtained by means of the proposed method have increased life time and reliability, and can be used in perspective gas turbine engines.
EFFECT: method provides the possibility of obtaining large-sized items of hot path of GTE from large ingots, prevents melting of ingot during continuous heating by homogenisation temperature.
