Modeling of Dendritic Grain Solidification
Résumé
Three different modeling approaches for grain structures formed during solidification of metallic alloys are presented in this article. They are direct modeling of dendritic structure, direct modeling of grain structure, and indirect modeling of grain structure. For each method, the main construction bases, the scale at which it applies, and the mathematical background are presented. For the purpose of comparison, simulations are conducted for a single equiaxed dendritic grain. More illustrative applications are gathered in the article "Formation of Microstructures, Grain Textures, and Defects during Solidification" in this Volume.
