ISING MODEL FOR PHASE SEPARATION IN ALLOYS WITH ANISOTROPIC ELASTIC INTERACTION--II. A COMPUTER EXPERIMENT

摘要

When a metallic alloy is quenched into a miscibility gap, a mixture of two phases develops, whose domain structure then coarsens because of the interfacial energy between the two phases. This spatial arrangement of the domains and the rate at which they evolve may be strongly influenced by elastic interactions. In a recent paper, the authors described a method for simulating the effect of anisotropic elastic interactions in a two-dimensional !sing model of a cubic alloy, using Kawasaki dynamics with the elastic interactions represented by a long-range two-body interaction potential.
