METHOD OF FORGING THE THERMOMECHANICAL PART MADE OF TITANIUM ALLOY Russian patent published in 2014 - IPC B21K3/00 C22F1/18 

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 T_β of conversion into beta-phase. Note here that at least one ingot rough forging step is effected at temperature T₁ lower than temperature T_β of 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 T₂ higher than temperature T_β of conversion into beta-phase. Produced forged piece is cooled down.

EFFECT: forged piece with fine and homogeneous grain size of about 50-100 mcm.
