<p>This document is a note on the Cahn solute drag model based on recent work in the literature. The solute drag models, in general, predict the magnitude of retardation of grain boundary migration due to solute segregation. An overview of classical solute drag model by Cahn is first presented. This is followed by some notes on the model, including a modified phenomenological model proposed by the author and a discussion on the solute drag model for the case of solutes with inhibited diffusion at the boundary. A C code that was used to solve the Cahn model numerically is included and available for download on github</p>
