The state of intermetallic compounds Al3Sc, Al3Zr, Al3Hf and slag shots introduced by high-temperature exchange reactions of corresponding fluoride-chloride salts with liquid aluminum has been studied. The particle size and segregation direction during centrifugation and filtration of melt have been examined by microscopy and local X-ray analysis methods. The dispersoids formed during decomposition of solid solution are strong phase reinforcers.
