Zirconium based alloy is a new type structural material with high specific strength and good comprehensive properties. In this article, quasi-static compression at room temperature and dynamic compression under various temperatures were performed to a new zirconium-titanium alloy. It was found that this alloy showed good strength and plasticity, and the strength increased and plasticity decreased with increasing strain rate or decreasing temperature. A constitutive model under dynamic compression was established based on Johnson-Cook model, and accorded well with experimental results.
