Notes:
Nd2Fe14B/α-Fe nanocomposite powders with a nominal composition of Nd12Fe82B6were prepared by HDDR combined with mechanical milling. The microstructure of both theas-disproportionated and the subsequently desorption-recombination annealed alloy powderswas studied by Mössbauer spectrometry and TEM. The magnetic properties were investigatedby VSM using bonded magnet samples. The results showed that the annealing temperature hadsignificant influence on both the recombination kinetics and the grain size of the Nd2Fe14B/α-Fenanocomposite phases, and the bonded magnet samples presented the best magnetic propertieswhen the nanocomposite powders were prepared by annealing at 760℃ for 30 min
