Method of producing a rare earth bond magnet

摘要

A method of producing a rare earth anisotropic bond magnet comprising the steps of: melting an aloy composed of 10-30 atom % of R (wherein R designates at least one rare earth element including yttrium), 2-28 atom % of boron and 65-82 atom % of M (wherein M designates at least one of iron, cobalt and nickel) and rapidly cooling the melted alloy to produce powder material, subjecting the material to stamping at the temperature of 300 DEG -900 DEG C. in an inert gas atmosphere to pulverize and press the material to a scaly shape and cooling the pulverized material so that a magnetic anisotropy is produced in the vertical direction relative to the pressed surface.
