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
