Notes:
Since titanium alloys are the most promising structural materials for the high velocityvehicles, the impact tensile strength of the materials is presently investigated. Three kinds ofaging treatments on the beta-titanium alloy were performed, and the tensile deformation behaviorswere identified in the wide range of the temperature and the strain rate. The stress-strain relationsof the titanium alloy significantly depend on the temperature and the strain rate investigated.Thermally activated process concept was applied to explain the experimental results, and thestress-strain relations at high strain rates were well understood with taking account of adiabaticheating effect. It has been found that the stress-strain curves depend on the microstructures, whilethe temperature and the strain rate effects are almost independent of the different aging treatments
