The solidification of metallic alloys gives ri se to the formation of dendritic grains. ln order to study the influence of the grain structure on segregation, a mode! has been developed that couples cellular automaton (CA) and finite element (FE) methods. The CA method simulates the development of the grains while the FE method solves the conservation equations that govern the evolution of the macroscopic variables. The coupling scheme between the CA and FE methods is defined to account for the movement of the grains, the approximation of a fixed sol id being used within the FE method. The fall of NH4CI crystals agrees with the measured grain sizes and, partially, with the sedimentation velocities. The simulation of the solidification of le...
