The theory of drag exerted on dislocation kinks by statistical density fluctuations of impurity atoms was generalized to the case of solid solutions. The conditions of the transition to anomalous kink drift, which was characterized by a non-linear time (t) dependence of the displacement x (x  tδ, δ < 1), were obtained. The related consequences for the dislocation mobility and the plastic flow of a solid solution were derived.
