Abstract
A compact survey is given of the processing of high-performance perman ent magnet materials, which are based on the intermetallic compounds S mCo5, Sm2Co17 and Nd2Fe14B. In addition, the present development state of magnets based on the recently discovered Sm2Fe17N3 phase is compil ed. Besides the commercial manufacturing technologies, powder metallur gy including sintering and rapid quenching, novel processing routes, i .e. mechanical alloying, hydrogen treatment and hot working of cast in gots, are also covered.
