A new equation of state for aluminum

Abstract

A new equation of state (EOS) has been produced for aluminum, which accurately reproduces experimental data for both the liquid and solid states. It also has a melting transition that reproduces measurements of the temperature vs pressure along the melt line. The liquid part of the EOS was calculated with the soft-sphere model for liquid metals, and the solid EOS is based upon a Birch-equation cold curve and Grüneisen thermal contributions. The range of the table extends from room temperature to 1.6 eV and from densities of 10−3–103 g/cm3.
