Abstract

A high-strength dual-scale structure titanium alloy, a preparation method therefor, and an application thereof, belonging to the technical field of alloy processing. The composition system of the titanium alloy is Ti—Nb—Cu—Co—Al, the atomic percentage of the various elements being 58˜70% Ti, 9˜16% Nb, 4˜9% Cu, 4˜9% Co, and 2˜8% Al. The microstructure comprises a dual-scale coexistence of micro-crystal isometric bcc β-Ti and ultra-fine crystal isometric bcc β-Ti, and a dual-scale coexistence of micro-crystal strip fcc CoTiand ultra-fine crystal isometric fcc CoTi, or an ultra-fine crystal strip fcc CoTitwin crystal is distributed along a boundary of a dual-scale substrate, the dual-scale substrate being a nano needle-shaped martensite a' phase dispersed within micro-crystal bcc β-Ti. The mechanical properties of the titanium alloy are significantly improved, and the titanium alloy may be used in fields such as aerospace and aviation, weaponry and sports equipment.
