The Parameters of Noble Metal and Calculations of Dilute Solution Heat for Noble Metal Binary Alloys

Abstract:

The modified embedded atom method (MEAM) has been applied to parameters calculated for noble metals Cu, Ag Au, Ni, Pd, Pt, Rh, Ir. The parameters of those elements were obtained. The elastic constants, mono-vacancy formation energy, energy difference between face central cubic structure and body central cubic, binding energies of divacancy were calculated. The dilute solution heat of noble binary alloys were also calculated with the present MEAM model. The calculated results were compared with the available experimental data and the results of other theories, which the agreement is reasonable.

Key words:modified embedded atom method; noble metal binary alloy; dilute solution heat
