Continuum modelling and representations of interfaces and their transitions in materials

Evidence for internal and external interface transitions in ceramics and metals is copious. The work described here lays out a framework for predicting interface transitions and including them on bulk phase diagrams. Advances in understanding possible grain boundary transitions in singleand binary-component materials have been made with energetics modelled with the phase-field model due to Kobayashi, Warren and Carter. Analyses inspired by Cahn’s critical point wetting work allowed the exploration of the stable, metastable, and unstable grain boundary compositions a b e f ©
