Abstract: A set of embedded-atom method (EAM) potentials for Al-Mg alloys are developed using the "force matching" method. The potentials are fitted to both experimental data and a massive quantum mechanical database of atomic forces at finite temperatures. Using the potentials, Monte Carlo simulations are performed to study Mg segregation at different low-index surfaces of an Al alloy with 1–10 at% Mg. Surface enrichments of Mg of the order of 80% are found, and the segregation behavior is generally anisotropic. A set of discrete lattice-plane calculations, based on the nearest-neighbor broken-bond model corrected for strain energy, are shown to drastically reduce the anisotropy of surface segregation.

Notes: To make the mg-al-set.txt file compatible with the eam/alloy style in LAMMPS, replace line 4 with "2 Mg Al" and the "D"s with "E"s in the numbers. This has been done in mg-al-set.eam.alloy.
