ABSTRACT:
A method of making a light metal-rare earth metal alloy includes mixing a light metal powder, such as aluminum powder, with a finely divided rare earth metal-containing compound, such as scandium oxide, creating a billet by subjecting the mixture to cold isostatic compaction. The billet formed from the mixture of aluminum powder and rare earth metal-containing compound is preferably sintered at a temperature of about 600.degree. C. to 800.degree. C. and preferably about 640.degree. C. to 680.degree. C., and subsequently feeding the billet to a molten aluminum bath. This method facilitates conversion of in excess of 95% of the rare earth metal oxide to the aluminum-rare earth metal alloy. The rare earth metal may be scandium.
