A new multiphase wide range Equation of State for Nickel

ORAL

Abstract

A new equation of state for Nickel has been built and entered in the SESAME database. The EOS was built by Opensesame, based on the multiphase approach. Magnetic effects, derived from the experimental heat capacity, were included by an extra term in the electronic free energy. The solid phase was fitted to available experimental data for thermal expansion, heat capacity and bulk modulus and to data from new DFT calculations of the cold curve and phonon dispersions. The low temperature liquid was calculated, based on the V-T theory approach, from DFT data for the cold curve in the liquid. The high temperature liquid was fitted to new QMD calculations.
