Abstract

We use a pseudopotential and thermodynamic perturbation theory to study the thermodynamic characteristics of metallic Mg and Zn melts. A system of solid spheres is selected, to be the ground state. Our calculations of the melting temperature, entropy, and volume are in good agreement with experiment, and the calculated results are insensitive to the choice of pseudopotential. As the temperature is lowered the diameter of the solid spheres and the packing density increase. In addition, there is a marked decrease in the melt's self diffusion coefficient, reflecting the possibility of forming an amorphous structure.
