A cast alloy includes aluminum and from about 5 to about 30 weight percent of at least one material selected from the group consisting of cerium, lanthanum, and mischmetal. The cast alloy has a strengthening AlXintermetallic phase in an amount in the range of from about 5 to about 30 weight percent, wherein X is at least one of cerium, lanthanum, and mischmetal. The AlXintermetallic phase has a microstructure that includes at least one of lath features and rod morphological features. The morphological features have an average thickness of no more than 700 um and an average spacing of no more than 10 um, the microstructure further comprising an eutectic microconstituent that comprises more than about 10 volume percent of the microstructure.
