Solute drag in grain boundary migration and phase transformations

Abstract [en]

Cahn's equation for solute drag has recently been applied to phase transformations but the method of application has been disputed. A new equation for solute drag is now proposed, which is more general and applies to multicomponent systems. It yields the same result for the migration of grain boundaries but a different result for phase transformations. It has the advantage of being equivalent to the approach based on the dissipation of Gibbs energy. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
