In this work, numerical method approach has been used to simulate the solidification parameters
of an eutectic aluminum-silicon alloy in chilled metallic mould with copper. The approach is based on
the solution of heat flow equations of the casting and mould. In addition, the latent heat is treated as a
boundary condition between the liquid and solid phase. The results showed that different behaviors of
solidification parameters are obtained along the casting. Furthermore, the simulation approach of
solidification parameters in conjunction with the microstructure indicated that it is possible, to a large
degree, giving a knowledge about the microstructural features for any alloy system.
