Abstract
The physical principles and modern modeling approaches for phase separation in binary alloys are reviewed. A fundamental distinction between the different simulation models is their description of the moving interface during the separation process. The interface between the phases is either atomically rough, or a diffuse interface with a smooth transition between the phases, or finally a sharp geometric interface with a discontinuous jump of the bulk properties of one phase to the other. Advantages and disadvantages of the these microscopic, mesoscopic and macroscopic modeling approaches are presented. Concerning examples given some emphasis is put on the influence of elastic interactions caused by a misfit between the phases on the transformation process.
