Addition of Zr to cast Mg--rare earth metal alloys results in a marked degree of grain refinement and a significant improvement in strength and ductility at temperatures up to 400 deg F. The strength properties and creep resistance of Mg--didymium-- Zr alloys are markedly superior to those of Mg-- Mischmetal--Zr alloys. Results of studies on alloys containing various proportions of Mischometal and didymium, and cerium and didymium, are also presented. In general, both in Ce--didymium and Mischmetal--didymium alloys the strength properties increase with increasing didymium content. (auth)
