Precipitate coarsening in multicomponent systems [PDF]

Scripta Materialia, 2002
Abstract Expressions to obtain composition shifts due to capillarity are presented when the chemical potential shifts of the precipitate phase are taken into account. These are applied to calculate the precipitate coarsening kinetics in multicomponent systems, showing dependence on the solution thermodynamics followed by the continuous phase.
