| Abstract Scope |
The aluminum alloy manufacturing process is increasingly expected to achieve both greenhouse gas (GHG) emission reduction and resource circularity. Focusing on the casting process, which accounts for a significant portion of energy consumption, horizontal continuous casting is advantageous in terms of both energy efficiency and equipment compactness. Furthermore, it is important to control the solidification microstructure in casting processes that accommodate the presence of impurity elements such as Fe and Mn derived from recycled scrap.
In this study, the effects of Mn addition and casting cooling rate on the casting microstructure were investigated using Al-Mg-Si aluminum alloys, which are widely used in industrial applications. Experimental observations obtained from various types of microscopy were compared with results from phase-field simulations performed using MICRESS, coupled with a CALPHAD-type thermodynamic database, to analyze the microstructural evolution of the material. |
