Excellent strength-ductility balance of a titanium alloy via controlling stress-induced ω transformation assisted by α-β hybrid structure

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

Automated summary

To achieve a balance between strength and ductility in a novel titanium alloy Ti-6Mo-3.5Cr-1Zr, the transition of microstructure from stress-induced beta to omega phase was intentionally retarded by designing an alpha-beta hybrid structure. Through microstructure optimization, the titanium alloy exhibited outstanding quasi-static tensile properties, with a yield strength of approximately 825 MPa, true tensile strength of approximately 1171 MPa, and total elongation of approximately 29.7%.
