Compendium About Multicomponent Interdiffusion in Two Dimensions

Abstract Interdiffusion between dissimilar solids can change the properties of joined materials. Although much work has been done to study experimentally and theoretically interdiffusion in one-dimensional (1-D) diffusion couples, studying two-dimensional (2-D) or three-dimensional (3-D) remains a challenge. In this article, we report an experiment develop model multicomponent system 2-D geometry. The results (concentration maps profiles) are compared with data obtained by modeling numerical simulations. It is assumed that satisfies Vegard’s rule coefficients composition dependent. To multidimensional drift, take benefit concept drift potential. A nonlinear parabolic-elliptic strongly coupled differential equations formulated implicit difference method, preserving rule, applied
