FIELD: metallurgy.
SUBSTANCE: initial rod blank is shaped. Then, isothermal forming of pre-lubricated and preheated shaped blank at hydraulic press. After cutting of flesh, blank alphatised layer is subjected to dimensional chemical etching and vacuum treatment. Then, heated blank is straightened by isothermal heat setting at heated die. Heat setting temperature is lower than that of vacuum thermal treatment by 20-80°C. Curing at 2 kgf/mm2 makes at least 3 minutes.
EFFECT: removal of residual strain, ruled out warping, lower input of machining jobs.
