Microscopic Phase-Field modeling of hcp|fcc interfaces

Autor: Marc-Antoine Louchez, Alexandre Legris, Rémy Besson, Ludovic Thuinet

Publikováno v: Computational Materials Science. 132:62-73

Heterophase prismatic hcp | fcc interfaces, playing a key-role in many alloy phase transformations, are difficult to analyze at the atomic scale, due to the presence of dislocations inducing long-range elastic fields. This features being best account

In the context of Al and Mn-doped ferritic steels, we progressively elaborate an atomic-scale energy model to reproduce the thermodynamic behaviour of quaternary Fe Al Mn C on a bcc lattice. This model is built on physical concepts: DFT calculations,
