Abstract
We describe a mean field, free energy model that allows the computation of realistic phase diagrams for a particular set of ordering transitions in face-centered-cubic (FCC) binary alloys. The model is based on a sixth-order Landau expansion of the free-energy function in terms of the three noncouserved order parametrs that describe ordering on the underlying FCC lattice. When combined with appropriate gradient-energy terms, this model will allow the self-consistent calculation of energetic and kinetic anisotropies of phase boundaries in future work.
