AI Technical Summary
Traditional titanium alloy manufacturing processes are prone to problems such as inversion of strength and plasticity, gradient distribution of FCC phase, and residual stress concentration under high oxygen content conditions, which limits their application in high-end fields.
By employing electron beam additive manufacturing, a steady-state thermal field is formed in a vacuum environment using a preheated substrate at 700℃~800℃, retaining the BCC phase, and inducing phase transformation through tensile deformation treatment, a high-strength and high-toughness oxygen-rich titanium alloy is obtained.
This approach achieves a synergistic improvement in the high strength and high plasticity of high-oxygen titanium alloys, simplifies the process flow, reduces production costs, avoids negative effects such as grain coarsening, and provides a high-strength and high-toughness integrated manufacturing path for complex components.
