High strength titanium alloy(tensile strength UTS at RT is over 1100MPa) is an important research branch of titanium alloys. In order to meet the requirement, different high strength titanium alloys have been researched and developed in China. This paper is briefly introduced the R&D on high strength titanium alloys and their applications in China, for example, TC21 — high strength (UTS ≥ 1100 MPa) high toughness Ti-alloy with damage tolerance, Ti-1300 — extral high strength (UTS ≥ 1300MPa) and high toughness Ti-alloy,Ti-12LC — low cost high strength Ti-alloy, Ti-5321 — high strength (UTS ≥ 1200 MPa) and high toughness Ti-alloy, Ti-1500 — extral high strength (UTS ≥ 1500 MPa) Ti-alloy, and so on.
