Abstract

The microstructure of ternary alloys in the Al rich corner of the AlCuSi system were analyzed in order to determine the solidification path in the different structural regions expected from the equilibrium phase diagram. The analysis was based on theoretical models developed in the literature for solidification of simple ternary eutectic system alloys under simple lever rule assumptions. Optical microscopy was used to study the microstructure formed in each case. The observations were consistent with model predictions, providing in that way an example of a methodology for use in ternary and multicomponent alloys.
