Abstract
It is shown that the inhomogeneity of the grain boundary (GB) i.e. the effect of the distribution of different lattice sites on the heats of interaction with species, leads to nonlinear GB penetration plots (in Fisher's coordinates). The sign of curvature and the values of deviat ion from a straight concentration profile depend on the interaction pa rameters (the maximum and minimum values of the interaction heat). The results of numerical calculations are discussed.
