摘要

En 中文

The effects of four causes of deviation from local equilibrium at migrating phase interfaces are illustrated with molar Gibbs energy diagrams and using the sharp interface model. The conditions during solidification and melting are compared. In particular, it is examined when the composition of a growing phase can move inside the two-phase field. (C) 2003 Acta Materialia Inc.
