摘要

To realize strength-ductility balance in a novel titanium alloy Ti–6Mo-3.5Cr–1Zr, the microstructure transition of stress-induced β→ω was intendedly retarded by design of α-β hybrid structure. The outstanding quasi-static tensile properties with yield strength of ∼825 MPa, true tensile strength of ∼1171 MPa and total elongation of ∼29.7% was obtained via microstructure optimization.
