Abstract

Hydrogen processing (HD + HDDR) is used to recycle Nd-Fe-B sintered magnets yielding anisotropic resin bonded magnets (RBM). HD produces single-crystalline powders from the sintered magnets. HDDR improves the magnetic properties by producing ultrafine grained, highly textured polycrystals. RBM produced from optimally processed recycled material shows comparable magnetic properties to non-recycled RBM.
