AI Technical Summary
Existing β-titanium alloys suffer from complex cold forming processes and insufficient plasticity when preparing thin-walled parts, making it difficult to meet the requirements of high-precision and high-quality processing. Furthermore, the addition of Fe and Cr elements leads to the precipitation of brittle phases, which limits their application in thin-walled components.
By rationally selecting the addition amounts of β-stabilizing elements Mo, Nb, and V, and controlling the content of α-stabilizing element Al, a metastable β-type titanium alloy was developed. The alloy was prepared by vacuum arc furnace melting, multiple forging, and heat treatment processes, resulting in a titanium alloy with high strength and high plasticity matching, suitable for cold forming.
It achieves efficient cold forming of thin-walled titanium alloy parts with tensile strength greater than 1350MPa, elongation greater than 13%, and cold deformation of over 90%, meeting the processing requirements of high-quality thin-walled components.
