Abstract Scope Approaches for recycling rare earth element (REE)-based intermetallic alloys will be presented. Recycling offers alternative/supplementary manufacturing materials sources by reinserting manufacturing wastes or end-of-life products into the manufacturing chain. Since manufacturing wastes are generated in manufacturing facilities, they help to eliminate difficulties in collecting recycling feedstock materials. Swarfs are wastes generated during cutting/grinding/polishing operations. During manufacturing, 30%–70% of REE magnet alloys can be generated as swarfs. Magnet swarfs are often contaminated and oxidized and therefore difficult to be directly reinserted into the manufacturing process. This talk will present metallurgical approaches for recycling magnet swarfs including directly reusing the swarfs for magnet manufacturing. Approaches for removing surface contaminations to facilitate direct reuse will be discussed.
