Abstract (en)
[origin: EP0066348A2] A method for producing magnets from powdered magnetic alloy. The method comprises aligning a particle charge of magnet alloy within a container, which aligning may be achieved by use of a pulsating magnetic field; and consolidating the charge after alignment to a density in excess of 95% of theoretical density as by cold or hot isostatic pressing, or a combination thereof.
