FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used in producing discs with ''blisk''-type vanes in isothermal and superplasticity conditions. In compliance with first version, heated billet is placed in isothermal mould comprising container and ceramic shaping elements. Billet is deformed by ball-tipped made die. Note here that vane is shaped by extruding billet material in cavity between shaping elements. Finished disc with vanes is withdrawn from mould by destructing ceramic elements. In compliance with second version, vane is first made and placed in isothermal mould. Note here that vanes are isolated by ceramic inserts while valve butts are arranged between two plates. Both plates and vane butts are deformed together in ball-tipped made die in isothermal and superplasticity conditions. Note here that deformation degree exceeds 20%. Note also that deformation rate makes (10-2 -10-3) s-1.
EFFECT: expanded process performances, higher quality.
