Modelling the influence of grain-size-dependent solute drag on the kinetics of grain growth in nanocrystalline materials
TL;DR: In this article, the authors modified the Burke equation to take into account a linear dependence of grain-boundary pinning on grain size, and the form of the resulting grain growth curve is surprisingly similar to Burke's solution; in fact, a constant rescaling of the boundary mobility parameter is sufficient to map one solution approximately onto the other.

TL;DR: In this paper, the authors describe a strategy for reducing or eliminating the driving force for grain growth in nanocrystalline materials via the deliberate segregation of solute atoms into the core region of boundaries.
