摘要： A hard magnetic material formed of material powders made of a R—Fe—N compound containing a light rare earth element as R, or material powders made of a Fe—N compound is used as material powders. There is formed a compact in which a density of the hard magnetic material powders differs between an outer face side portion and an inside portion of the compact such that a rate of progress of powder bonding due to microwave heating is higher in the inside portion of the compact than in the outer face side portion of the compact when an outer face of the compact is irradiated with microwaves. Then, the outer face of the compact is irradiated with the microwaves to cause the microwave heating, thereby bonding the hard magnetic material powders by oxide films which are formed on the hard magnetic material powders.

摘要： A method to increase the volume fraction of magnetically aligned material in rare earth (RE), iron, boron type anisotropic permanently magnetic material includes forming an adaptively shaped fully dense substantially magnetically isotropic preform from relatively coarse powder particles of melt spun alloy with a very fine grain Re.sub.2 Fe.sub.14 B phase. The preform is heated and die upset to provide uniformity of strain in the perform as it is conformed to the die thereby to cause an increased percentage of the crystallites to be oriented along a crystallographically preferred magnetic axis which increases the energy product of a resultant magnet.
