 This paper examines the effect of chromium on segregating iron-based phases in aluminum-silicon alloys. Iron is a common impurity that can be difficult to remove from molten alloy, but adding chromium can reduce its negative effects. Experiments were conducted and analyzed to determine how much chromium was needed to prevent segregated iron-based phases from forming. The results showed that more chromium was required for higher iron contents, and that this increased chromium caused the formation of sludge particles. In conclusion, chromium can be used to reduce segregation of iron-based phases in aluminum-silicon alloys. This article was authored by Dana Balabrkova, Lukas Richterak, and Vladislav Orlovichs.
