TL;DR: In this paper, the authors proposed a mechanism in which differences in the diffusion coefficients of the diffusing species along the grain boundary cause a self-sustaining climb of grain boundary dislocations and motion of their associated grain boundary steps.

TL;DR: In this paper, applications of the Gibbs-Konovalov equation to congruent transformations, retrograde solubility, phase boundary inflections, and solid-liquid equilibrium are discussed.
Abstract: One hundred years ago, Konovalov developed and tested the rule that at a congruent transformation the phase boundary reaches an extremum. An important equation for the slopes of phase boundaries, derived by Gibbs five years earlier, provides the underlying theoretical basis for the rule, which is still commonly ignored. Applications of the Gibbs-Konovalov equation to congruent transformations, retrograde solubility, phase boundary inflections, and solid-liquid equilibrium are discussed.
