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

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.
