摘要：
A new approach to describing anomalous grain growth based on the idea of transition of migrating grain boundaries into a highly nonequilibrium state is proposed. The effect of the grain-size scatter and the initial dislocation density on the evolution of this process has been considered. Conditions that are required for the realization of an anomalously rapid grain growth have been analyzed.
