A method for improving the uniformity of the process Forging Titanium ingot forging billet tissue

The present invention discloses an improved process of large titanium alloy ingots Forging Size forging stock a large thickness uniformity of the tissue. Titanium alloy, respectively, first at a heating temperature of 1150 deg.] C and 1100 ℃ Forging conditions fire 2 times, followed by heating at a temperature in the β transformation temperature of 20 ℃ ~ 45 ℃ views of a fire condition forging, then be a fire time forged at a heating temperature of not less than β transformation point temperature of 30 ℃ ~ 80 ℃ conditions, and finally at a temperature of 2 to 5 thermal times forging under 20 ℃ ~ 45 ℃ the β transformation point temperature or less, large organizations to obtain a homogeneous alloy forging stock. This process is suitable for type [alpha], α-β type titanium alloy or beta] near large ingot blooming and forging blank is forged, in order to meet the high requirements of uniformity of microstructure and properties required for a titanium alloy aircraft components or for producing large forgings .
