摘要：

Permanent magnets are used in countless applications. Rare earths availability is reduced, while the demand is continuously increasing, together with the prices. Many hydrogen-based methods of recycling NeFeB magnets have already been adopted and studied. Three alternative processes are here proposed, based only on mechanical treatments. The impact of the mechanical procedures is analyzed with reference to the magnetic characteristics and compared with a commercial powder typically adopted in bonded magnets realization.
