Abstract

PURPOSE: To manufacture permanent magnets of high strength, high performance, by forming intermetallic compound particles comprising one or more members selected from the group consisting of REM including Y, Sc; Co, Mn, Fe; and one or more transition metals other than Co, Mn, Fe, Cu, and Cr, using resin or metallic alloy as a binder.
CONSTITUTION: Every components are melted in a high frequency heating furnace and cast into an ingot having a composition shown by the formula I, then heat treated suitable to adjust crystal structure and to develop addn. effect of T elements. The ingot is pulverized to 5W30μ by a ball mill etc. The particles of RCo type intermetallic compounds thus obtained are formed by use of org. resin or metallic alloy of m.p. not higher than 1,000°C as a binder. In the formula I, u, v, w, and z are defined as follows: O<u≤0.30, 0.05<v<0.05, 0.001<w≤0.20, u+v+w< 0.50, 7.5≤z≤0.90, R being one or more members selected from the group consisting of REM including Y, Sc, and T being one or more members selected from the group consisting of transition metals other than Co, Mn, Fe, Cu, Cr.
