Comparison of 2D and 3D simulations of solidification of binary and ternary Al-based alloys under RMF

Two-dimensional and three-dimensional numerical simulations of solidification of Al-7wt%Si and Al-7wt%Si-1wt%Fe under RMF stirring were performed and compared with the corresponding experimental data. It is demonstrated that 2D simulations provided segregation pattern similar to experimental data. Yet, the segregation patterns at the end of simulations performed in 2D are slightly different compared to the segregation map obtained in 3D simulations.
