Compressive Property and Equation of State of 4.2Ni2.45Fe0.35CoW Alloy under Pressure from 100 GPa to 500 GPa

摘要: 用二级轻气炮驱动飞片技术及对称碰撞技术，测量了两相合金4.2Ni2.45Fe0.35CoW（以下简称93W）的雨贡纽线。其压力范围为100~500 GPa。实测的冲击波速度D和粒子速度u可用直线关系式D=4.008+1.277u (km/s)描述。实验结果与用混合物雨贡纽线叠加原理的计算结果符合甚好。文中还给出了由实验数据计算得到的物态方程数据。Abstract: Investigation of compressive property for tungsten alloy 4.2Ni2.45Fe0.35CoW (93W) in the pressure ranging from 100 GPa to 500 GPa was performed by using a two-stage light-gas gun and symmetric impact technique, The relation between shock velocity, D, and particle velocity, u, can be expressed by D=4.008+1.277u (km/s), which is in good agreement with the Hugoniot prediction by a different method of Hugoniot for mixture materials.
