Abstract

It is shown that nonlinear segregation effects (saturation, interaction of species) lead to nonlinear grain-boundary penetration plots. If the diffusion penetration depth is larger than a critical value, the concentration profiles become linear. The sign of the curvature and the deviation from a straight concentration profile depend on the segregation parameters (segregation energy, energy of mixing). As an illustration results of numerical calculations are presented and discussed.
