Research and Development of Rare Earth-Transition Metal Alloys as Permanent-Magnet Materials

Abstract

The significant accomplishments of investigations conducted over the past three years are summarized. Topics covered include: the metallurgy and magnetic properties of the rare earth-cobalt-iron alloys R2(Co(1-x)Fex)17 with R = Y, Ce, Pr, Nd, Sm and MM (Ce-rich mischmetal); the rare earth-cobalt binary phase diagrams Ce-Co, Pr-Co and Nd-Co; the sintering and magnetic properties of the mixed rare earth-cobalt alloys R(1-x)PrxCo5, R = Sm, Didymium and R(1-x) NdxCo5, R = Pr, Sm, Didymium.
