Model describing the nucleation, growth and motion of groups of grains

A model based on a granular dynamics approach has been developed in order to describe the nucleation, growth and movement of groups of grains in the DC casting process. The outputs of the model consist in the local average grain density, grain size, secondary dendrite arm spacing, and grain morphology at the outlet of the product. Moreover, the numerical tool, which has been developped, allows a new way to analyse the history of the grains in the DC-casting of aluminium process. This model can also provide the local grain density as an input to the as-cast microstructure model developed at EPFL. The grain density determines to a large extent the morphology of the grains and thus the repartition of intermetallic phases.
