发明名称 Method for producing dies for use in compacting permanent magnet alloy powders
摘要 Producing a die for use in compacting permanent magnet alloy powder by placing a quantity of a magnetic or nonmagnetic alloy, which may be stainless steel, cobalt- or nickel-base, or a magnetic or nonmagnetic mixture of one of these alloys and carbide particles in a container, heating the particles to an elevated temperature and hot-isostatically compacting the particles at the elevated temperature to obtain a fully dense die blank and forming a die cavity in the die blank. Carbide particles may be mixed with the alloy particles. The die blank may have an exterior cladding of stainless steel.
