Abstract

The effect of alloying with aluminum and cerium on morphological features and production characteristics of eutectic alloys based on iron is studied. An aluminum content from 0.5 to 3.0% modifies particle shape from compact and rounded to particles with a very developed surface. A reduction in the segregation point of impurity elements, primarily sulfur and phosphorus, is observed on adding 0.05–0.16% of cerium. Cerium also promotes formation of spherical particles which provides good production characteristics.
