Abstract Today's focus in the aluminium industry is promoting a circular economy, thus meeting the US and the EU's ambition of reducing greenhouse gas emissions. This means replacing primary aluminium with post-consumer scrap, which contains larger quantities of intermetallic forming impurities, particularly Fe and Si, which are detrimental to mechanical properties. We need to develop new generations of impurity-tolerant aluminium alloys enabling reduced carbon footprint through increased recycled content. To meet this objective, it is necessary to deepen our understanding of AlFeSi secondary phase nucleation and growth during aluminium alloy solidification. In this work, model 6xxx recycling-friendly alloys were manufactured and unique in situ directional solidification experiments were performed. For the first time, nucleation and growth of alpha-AlFeSi and beta-AlFeSi intermetallics were observed in real time in thin samples of model 6xxx alloys. We discuss the effect of chemistry modification and solidification parameters on the AlFeSi phase nucleation and growth.
