Abstract

Hydrogenation and dehydrogenation of the Nd16Fe76B8 magnet are studied by X-ray diffraction analysis (XRD) and Mössbauer spectroscopy. The results of the samples treated under different hydrogen gas pressures at different temperatures are discussed. A special hydrogenation-dehydrogenation treatment of the Nd−Fe−B magnet cast can produce excellent isotropic magnet powders and the treated sample has passed a hydrogenation-disproportionation-recombination process.
