Abstract
A powder metallurgical method of producing metal bodies using spherical powder, produced by inert gas atomization, from magnetizable material with a particle size distribution closely approximating the so called Fuller curve for maximum density packing of spherical particles. Said powder is magnetized and filled into a form, which may take place before or after magnetization, said mixed and magnetized powder then sintered in said form with the exclusion of air, to produce a sintered body without communicating porosity.
