Abstract:The damage tolerance titanium alloys,such as Ti-6Al-4V ELI,TC4-DT,TC21 and TA15 ELI alloys,were summarized.The development process and the new study of damage tolerance titanium alloy were introduced.It pointed out that Ti-6Al-4V ELI alloy was successfully used in the airplane manufacture industry in foreign countries.However,TC4-DT,TC21 and TA15 ELI alloys were still under research in our country.The fracture toughness and fatigue crack propagation rate properties of TC4-DT,TC21 and TA15 ELI alloys were importantly discussed in detail.The lamellar microstructure was beneficial to improve the damage tolerance properties of titanium alloys.
