Sm(Co, Fe, Cu, Zr, C) COMPOSITIONS AND METHODS OF PRODUCING SAME

Title:

Sm(Co, Fe, Cu, Zr, C) COMPOSITIONS AND METHODS OF PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO2000026926

Kind Code:

A9

Abstract:

Carbon addition to the rapidly solidified, preferably melt spun, alloy system of Sm(Co, Fe, Cu, Zr) provides for good isotropic magnetic properties. Importantly, these alloys are nanocomposite in nature and comprise the SmCoC2 phase. Thermal processing of these materials can achieve good magnetic properties at lower temperatures and/or shorter processing times than conventional Sm(Co, Fe, Cu, Zr) powders for bonded magnet application.
