Abstract Scope |
The increasing demand for eco-friendly materials and stricter carbon emission regulations necessitate the use of recycled materials in various industries. Recycled aluminum alloys contain iron, which can lead to unintended microstructural changes. This study investigates the casting characteristics of alloys with varying Fe and Mn contents.
Using a phase-field model that incorporates CALPHAD-type free energy, we simulate microstructure formation and precipitation during solidification in AA 386 casting material and similar alloys with Fe and Mn impurities. The model helps analyze the impact of Fe and Mn on microstructures and examines methods to suppress the beta phase through compositional and processing adjustments. This research aims to optimize the use of recycled aluminum alloys while maintaining material performance. |
