本文采用铸造法制备了Ta 50-Zr 50和Ta 45-Zr 45-Nb 10合金。对两种合金进行了准静态和动态压缩试验，研究了Nb添加剂对Zr-Ta合金力学性能的影响。显微组织分析表明，两种合金组织相对均匀，晶粒内部均为微层状结构。Nb的添加提高了合金在不同应变速率下的强度，但降低了合金的塑性。通过数据拟合得到了两种合金本构方程的各个参数。将本构方程应用于理论模型中，模拟软件有助于预测不同应变率下合金的强度。
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.
