Preparation Technology of TC4ELI titanium alloy wires for high performance medical and therapeutic apparatus
The demand for the localization of high-performance titanium alloy materials for medical devices by con-ducting research on the full-process preparation technology of TC4ELI titanium alloy wires were addressed.Utilizing large-scale industrial production processes,it systematically investigates the effects of thermal processing and heat treatment on the microstructure and mechanical properties of TC4ELI titanium alloy wires.The research findings re-veal that when the annealing temperature is between 650 ℃ and 700 ℃,the yield strength exceeds 900 MPa.How-ever,when the annealing temperature surpasses 700 ℃,the yield strength falls below 900 MPa.Through the appli-cation of a"solution treatment+aging"heat treatment process,high-performance wire products are achieved,characterized by a yield strength Rp0.2 greater than 1100 MPa,tensile strength exceeding 1200 MPa,elongation a-bove 10％,and a reduction of area Z around 50％.The industrial"solution treatment+aging"heat treatment process scheme developed in this study is highly feasible and ensures stable product performance,supporting its ca-pability for industrial-scale supply.
