A study on the microstructures and tensile properties of new beta high strength titanium alloy

► Developed microstructure-property relationships for Ti-6Cr-5Mo-5V-4Al alloy. ► Optimized the heat treatment to obtain good balance of strength and ductility. ► The strength of the alloy can be hardened to 1600 MPa by direct aging. ► Provided quantitative data for the selection of property and microstructure.
