FIELD: metallurgy.
SUBSTANCE: heated billet is fitted in split female die with its inner shape mating the part configuration. Billet inner surface is subjected to mechanical effects by filler composed of heated casting aluminium alloy. Said mechanical effects are produced at 120-150 MPa. Removal of filler is carried out at 850-860°C.
EFFECT: enhanced performances.
