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

Abstract RU 2510680 C2

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 Tβ of conversion into beta-phase. Note here that at least one ingot rough forging step is effected at temperature T1 lower than temperature Tβ 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 Tβ 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.
