Abstract: The aim of this article is to provide a numerical tool, which is able to predict macrosegregation profiles during the solidification of ternary alloys. The solute profiles during the transient directional solidification of an Al-6wt%Cu-1wt% Si alloy were calculated taking into account secondary phase transformations, which occur along the corresponding solidification path. The simulations were compared with experimental segregation profiles determined along the length of a directionally solidified casting through X-ray fluorescence spectrometry measurements. A very good agreement between predictions and experiments has been observed.
