AI Technical Summary
Traditional methods for preparing Ti6Al4V titanium alloy slabs suffer from poor microstructure uniformity, high costs, and low production efficiency. Rolling costs are particularly high when there are small-batch customer demands, and the microstructure exhibits significant anisotropy after rolling.
By employing a high-low-high process, combining high-temperature transverse elongation and axial elongation at 22.5°, and forming in one step using a large precision forging machine, the refinement and uniformity of the as-cast structure are achieved by controlling the recrystallization temperature and heating time, thus abandoning the traditional multi-fire upsetting and free forging process.
The method achieves good microstructure uniformity in Ti6Al4V titanium alloy slabs, significantly reduces production costs, increases yield, shortens production cycle, reduces costs by 67%, increases yield by 5.4%, and enhances production flexibility.
