摘要

In this paper, Ta50-Zr50 and Ta45-Zr45-Nb10 alloys were compounded by casting. Quasi-static and dynamic compression tests were applied for both alloys, and also the role of Nb additive on the mechanical property of Zr-Ta alloy, was studied. The microstructure characterization demonstrated that both alloys had relative homogeneous structure with micro-laminate structure inside grains. The Nb additives increased the strength of the alloy by various strain rates, while the ductility of the alloys was decreased. The various parameters of constitutive equations for both alloys were obtained by fitting data. The constitutive equations are applied in theoretical models, the simulation software helps to predict the strength of alloy through various strain rates.
