Abstract
A local-nonequilibrium model for rapid solidification of highly underc ooled melts is proposed. The model predicts an abrupt change of the ef fective diffusion coefficient, the partition coefficient, and, hence, the solidification mechanism when the interface velocity is equal to t he diffusive speed.
