Zusammenfassung

Nowadays, there is an enormous variety of magnets that differ significantly in their geometry, performance specifications and alloy composition depending on the application and manufacturer. Direct reuse of Nd-Fe-B based magnets from old electrical appliances would be technically possible, but due to a lack of standardization of the magnets, this is not implemented in practice. The aim of this approach is to reprocess end-of-life Nd-Fe-B based magnets. Discarded magnets are processed by hydrogen decrepitation or rapid quenching of the melt into powder form, which can be reused for magnet produ...
