Simulation of grain structure and microsegregation of multicomponent aluminum alloys
during solidification is developed and numerically implemented. Input temperature
history for microstructure development is obtained from macroscopic simulation environment
for semi-continuous casting. Heterogenous nucleation is taken into account,
as well as anisotropic surface energy. The solution process is based on combination of
cellular automata and finite volume method. Using linearized phase diagram, qualitative
agreement of simulation results and experimental data for alloy EN AW-2011 is
obtained.
