发明名称 PRODUCTION OF RARE-EARTH PERMANENT MAGNET
摘要 PURPOSE:To obtain a well-balanced magnetic property by pressure-molding a mixed alloy powder in he magnetic field, sintering the molded body in a vacuum or atmosphere of inactive gas, and further applying aging heat treatment at such a low temperature as sintering temperature or below. CONSTITUTION:An A alloy is composed of an R<2>T<14>B phase mainly (R: at least one or more kinds of rare-earth elements including Nd, Pr and Dy mainly, T: Fe and Co). A B alloy contains R, Co, Fe, B and Ga, and is composed of an R<2>T<114>B phase and/or an R rich phase, and a combined phase with at least one or more kinds of RT<24>L phase, R<23> phase, RT<22> phase, R<2>T<27> phase and RT<25> phase. Thus a well-balanced magnetic property can be obtained.
