Abstract

The equilibrium configurations of vacancy containing Fe-Al, Fe-Cr-Al and Fe-Mo-Al alloys will be investigated by Monte Carlo simmulations in the grand-canonical ensemble. The interaction parameters for the simmulations will be taken from previous publications by the author (R. N. Nogueira and C. G. Schon, Intermetallics, vol. 13, 1233-1244 and 1245-1254, 2005). These interactions will be incorporated in the energy model of the Monte Carlo simmulations by means of long-range pair interactions. (AU)
