Metallurgical Processes in Multi-Component Rare Earth-Transition Metal Permanent Magnet Alloys

Abstract

The primary objective of this research has been to improve and extend the technology of 2:17 type permanent magnets. The research has proceeded by employing a model for the complex metallurgical behavior of these alloys. During the three year period of this research, we have succeeded in establishing a record value (BH)max=34 MGOe for energy product in uncompensated Sm(CouFevCuxZry)z magnets. This was achieved by increasing the Fe content to v=0.31-0.33 (28-30 at.%) while developing heat treatments to maintain the coercivity at high levels. (jes)
