摘要: 对一种新型的钽铌合金材料进行了冲击压缩特性实验研究，通过超声测量得到了其常态下的横波和纵波声速，进而计算得到了其相关的一些静态力学参量。通过二级轻气炮加载技术，得到其在60~196 GPa压力范围内的冲击Hugoniot线。这一测量结果与混合物叠加法估算的结果符合较好，并将这种新型合金材料的力学特性与两种钨合金材料进行了简单对比。比较结果显示，Ta-Nb合金材料是一种具有较好工程应用前景的材料。

Abstract: A new kind of Ta-Nb alloy has been studied. By means of ultrasonic measurement, its sound velocities of longitudinal wave and transverse wave were obtained, and some of its static mechanical parameters were calculated. Through shock compression experiments with a two stage gas gun, its shock Hugoniot curve in pressure range from 60 GPa to 196 GPa was obtained. The result was in good agreement with the calculation by a mixture model. The mechanical characteristics of Ta-Nb alloy with two kinds of tungsten alloy have been compared, which shows the dynamic behavior of Ta-Nb alloy is better than that of tungsten alloy.-
