It was demonstrated (using computer simulations based upon a general continuum model) that the diffusional interface sharpening in ideal binary alloys, found recently using deterministic kinetic equations and a discrete atomic approach, was still present even if stress development and relaxations during interdiffusion or the so-called built-in stresses (caused by lattice mismatch or thermal expansion) were also taken into account. It was therefore concluded that this diffusional sharpening, in systems with large diffusion asymmetry, was a quite widespread phenomenon.
