On-Site Speaker (Planned) Alan A. Luo
Abstract Scope Iron (Fe) has long been treated as a major “impurity” element in cast aluminum alloys, due to its often detrimental effect on the mechanical properties of castings with high Fe contents. Fe can form numerous intermetallic phases in aluminum alloys depending on other alloying elements and cooling rates during solidification. The size, morphology, and volume fraction of these Fe-containing intermetallics have a pronounced effect on the mechanical properties of aluminum castings. This talk presents thermodynamic assessments and experimental investigation of various microalloying elements in neutralizing/reducing the detrimental effect of Fe-containing intermetallics in cast aluminum alloys. This research provides a scientific foundation for increasing secondary alloy usage and scrap recycling in aluminum casting industry.
