Abstract

Simulation results of microstructure evolution in technical aluminum alloys are presented. The examples comprise solidification and further heat treatment of three different alloy classes, namely for the hypoeutectic alloy AA6061, the near eutectic alloy A356 and the highly alloyed, hypereutectic commercial alloy KS1295 being used in automotive applications. After a short introduction to the simulation models being applied — especially to the multiphase-field approach coupled to thermodynamic databases — the evolving microstructures are discussed in the context of the interplay between thermodynamics, kinetics, interfacial properties and nucleation.
