Abstract
The nation-disproportionation-desorption-recombination behaviour of Nd -Fe-B alloys has been studied by in-situ powder neutron diffraction an d thermomagnetic measurements performed under hydrogen gas. Decomposit ion temperatures have been determined in order to obtain partial or co mplete reactions. Intermediate phases have been observed. The recombin ation process is complete if performed at 860 degrees C for 20 min. Th e rate of iron present after recombination is temperature dependent.
