Equation of State of Hafnium at High Pressures in Shock Waves

The thermodynamic properties of hafnium under the high pressures obtained behind the shock wave front are described. A simple model in the form of a dependence of pressure on the specific volume and specific internal energy is proposed. The thermodynamic characteristics of the body-centered cubic (bcc) solid phase and melt of hafnium under high shock-compression pressures are calculated. The calculation results are compared with the available data of shock-wave experiments. The resulting equation of state of hafnium can be used in numerical simulation of the processes occurring at high pressures in shock waves.
