Abstract
We develop a multi-component phase-field model specially formulated to robustly simulate concentration variations from molar to atomic magnitudes across an interface, i.e.: partition coefficients in excess of 10 (superscript 10plus23) such as may be the case with species which are predominant in one phase and insoluble in the other. Substitutional interdiffusion on a normal lattice and concurrent interstitial diffusion are included.
