Interface conditions during diffusion-controlled phase transformations

Considerations of the driving force on the interface in diffusional phase transformations are usually limited to diffusion in the parent phase. Diffusion in both phases is now considered. Equations are derived for the calculation of the composition of the material crossing the interface and the driving force acting on the interface. (C) 2003 Acta Materialia Inc.
