摘要
The multiphase equation of states (EOSs) of both the solid and liquid phases of Al and Ta are presented.These EOSs are carried out on the basis of the Helmholtz free energy,where the ion vibration free energy is evaluated from the mean field potential (MFP) model we recently proposed [Physica B 406 (2011)4163].The calculated results show that our multiphase EOSs can give a good reproduction of the measured phase diagrams and other experimental data,including static high-pressure measurements,shock Hugoniots and the thermodynamic quantities of these metals.
