FIELD: process engineering.SUBSTANCE: invention relates to metal forming and can be used for production of turbo machine thermomechanical part from beta- and/or alpha/beta-titanium alloy. Forged piece of the part is made from titanium alloy ingot with temperature Tof conversion into beta-phase. Note here that at least one ingot rough forging step is effected at temperature Tlower than temperature Tof conversion into beta-phase. In forging, the ingot is plastically deformed to ensure local deformation at all points of at least 0.2. Produced ingot is cooled down and subjected to final fording at Thigher than temperature Tof conversion into beta-phase. Produced forged piece is cooled down.EFFECT: forged piece with fine and homogeneous grain size of about 50-100 mcm.14 cl, 3 dwg |
