Abstract

Scope of the present article is to review the current state of the art with respect to simulation of microstructure evolution based on the multiphase-field approach in technical alloy grades. Starting from a short overview about computational thermodynamics and kinetics and respective databases for technical alloys, an engineering approach to phase-field and multiphase-field models will be depicted in order to allow for a basic explanation of these methods—in general being developed by physicists and mathematicians—for materials scientists and metallurgists. These explanations are followed by examples of applications of the multiphase-field method to solidification and solid state transformations in steels, cast iron, superalloys, Al- and Mg-alloys, solders and other alloys and compounds. The article is concluded by a short description of present and future trends.
