Modeling of Dendritic Grain Solidification

Abstract: This article discusses the three different modeling approaches for grain structures formed during solidification of metallic alloys: direct modeling of dendritic structure, direct modeling of grain structure, and indirect modeling of grain structure. The main construction bases, the scale at which it applies, and the mathematical background are presented for each modeling approach. The article concludes with a table that presents a comparison of the main inputs/outputs, approximations, numerical methods, kinet… Show more

“…The modelling of this important transition has been much improved by numerical methods. For the computation of the ECT and CET transitions, the CAFE model was successfully applied [355,356]. It allowed the simulation of realistic microstructures in castings and welds and has become a standard simulation tool, for example for the single crystal selection (Figure 18) in turbine blade investment castings [356] or for twin roll casting [357].…”
