Grain boundary inhomogeneity and grain boundary heterodiffusion

Philosophical Magazine A, 1995
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 deviation from a straight concentration profile depend on the interaction ...

Grain boundary segregation and grain-boundary heterodiffusion

Philosophical Magazine A, 1992
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.
