Interface Energy and Phase Transformations: A Comparative Analysis of Cahn-Hilliard and CALPHAD-based Models in Ternary Substitutional Alloys

Wolfgang Flachberger, Thomas Antretter, Swaroop Gaddikere-Nagaraja +3

Diffusional phase transformations in alloys are modeled either by phase-field methods of Cahn-Hilliard type, in which a double-well free energy and a gradient term impose an interf…
