Abstract: An analytic modified embedded-atom model is presented.Using the model,the thermodynamic data,such as the dilute-limit heats of solution,formation enthalpies of disordered solid solutions,surface energies and surface segregation energies for Pd-Au alloy,are calculated.The results are in agreement with the experimental data and calculated data using ab initio theory.

Key words: embedded-atom method, dilute-limit heats of solution, formation enthalpies, surface energy and surface segregation energy
