It was recalled that Hillert had proposed a new solute-drag formula which was applicable not only to the migration of grain boundaries, but also to that of interfaces. Svoboda et al. had derived an expression, for the velocity of a migrating thick interface, by applying the principle of maximum dissipation. It was shown that expressions for the interface velocity, one obtained from Hillert's solute drag formula, and the other derived from the principle of maximum dissipation, were equal under steady-state conditions.
