Nowadays the majority of commercial alloys are multicomponent and multiphase systems. The understanding and prediction of microstructure formation in multicomponent alloys is complex, especially when multiphase reactions occur along the solidification path. Particularly, several efforts are directed towards controlling the amount, the morphology and the distribution of minority phases, formed in situ as particles or inclusions. Present research focuses on the investigation of the eutectic growth in ternary aluminium alloy. At certain solidification conditions the Al-Mn-Si ternary...
