Solid and liquid Gibbs free energies of Cu, Ag, Au, Ni, Pd, and Pt have been calculated through the use of the embedded-atom method, and the results are in good agreement with experiment. The melting points of the materials are calculated from the intersection of the solid and liquid free-energy curves. The values of the melting point are in excellent agreement for the noble metals and in reasonable agreement for Ni, Pd, and Pt. The thermal expansions of the solids are computed and the results are in excellent agreement with experiment over the entire temperature range.
