Liquid Metal and Solidification Processing 7.5 credits

The critical content is related to preparing aluminium alloys, including light metal scrap recycling technologies, melt refining, and impurity control to enable the sustainable management of circular materials. The fundamental mechanisms of solidification and different conditions for the formation of microstructure during solidification and casting defects will be taught. Finally, microstructural engineering, such as grain refinement and microstructural modification for desired properties, will be discussed. The course includes the following elements: - The effect of dissolved impurities and inclusions on the mechanical properties of metal products - Thermodynamics and transport properties relevant for the removal of dissolved elements and inclusions from molten metals and the addition of alloying elements - Industrial melt management practice for aluminium alloys and sustainable circular materials management - Solidification and refining - Microstructure formation through homogeneous and heterogeneous nucleation for grain refinement - Primary phase growth and morphological control with Interface stability and constitutional undercooling - Multiphase reactions such as eutectics and peritectic and modification - Mushy zone characteristics and their importance for casting defect formation
