Prediction of grain boundary chemistry in multicomponent alloys
Science and Technology of Advanced Materials: Methods, 2022 Hillert’s grain-boundary-phase (GBP) model is employed for predicting grain boundary (GB) chemistry in multicomponent alloys. The GB is approximated as a thin layer of a homogeneous phase with a constant thickness and its own Gibbs energy.
