Abstract

To predict the kinetics of the dissolution of binary second-phase particles in ternary alloys one needs detailed models to compute the displacement of the parent-product interface. To compute this displacement the diffusion equation for both alloying elements has to be solved. The boundary conditions at the parent-product interface are linked via an approximately hyperbolic relationship obtained from thermodynamic phase diagrams. The fluxes of the elements out of the particle are linked to maintain the stoichiometry of the particle during the entire dissolut
