Effect of cooling rate following β forging on texture evolution and variant selection during β → α transformation in Ti-55511 alloy
文献摘要：
The control of the post-forging cooling rate has been a key issue in the industrial production process of ti-tanium alloys.We investigated texture evolution and variant selection(VS)during β → α transformation through high-temperature compression experiments followed by quantitative control of varying cooling rates.Results show that post-forging cooling rates affect β grains,α variants,and α/β textures.The αprecipitation inhibits motions of β static recrystallization(βSRX)grain boundaries and thus leads to grain refining from 0.1℃/s to 0.05℃/s.Further analysis reveals that lamellae grain boundary widmanstattenα(αWGB)keeps growing rapidly within β-grain in an interface instability manner at 0.1-0.05℃/s.Most of α-phase with 50°-60°/<-12-10>is preferentially precipitated at β-medium angle GBs between 30° and 45° and strictly follows BOR with the side of of adjacentβ-grain with the same or similar{110}or{111}.Moreover,the texture type transforms gradually from RGoss{110}<1-10>to Brass{110}<1-12>from 25℃/s to 1℃/s.βSRX grains exhibit(102)[-201]texture,while the corresponding α has textures of<0001>//Z and<11-20>//Y from 1℃/s to 0.05℃/s.Our findings lay a profound theoretical foundation in microstructure evolution of near-β titanium alloy for industrial production.
