Embedded atom potentials in fcc and bcc metals

A new embedded atom potential has been proposed in this paper. The potentia l is expressed by simple functions and is applicable to the molecular dynam ics simulations of large atomic systems. The potential parameters are deter mined from the experimental data using the cohesive energy, Born stability, elastic constants, C-11, C-12 and C-44, the formation energy of a vacancy. In case of fee the stacking fault energy is also used to fit parameters. T he potential functions for copper, silver and gold for fee metals and for b cc metals Nb, Ta and Va are presented.
