Abstract
A method is provided for comminuting and mechanically magnetically orienting particles of hot worked rare earth-transition metal-boron alloy to make bonded anistropic magnets. The method involves comminuting a hot-worked body of the alloy to form platelet shaped particles, and applying pressure to the particles in a die in the absence of an external magnetic field.
