The effects of variations in the hydrogenation-disproportionation-desorption-recombination (HDDR) processing parameters on the size of Nd-Fe-B ultrafine powders were investigated. The ultrafine powders were fabricated by hydrogen decrepitation and jet milling of the HDDR alloys. Before pulverization, the crystal grain size of the HDDR alloys obtained by changing the HD processing temperature (T-HD) varied from 0.27 to 0.55 mu m, and decreased as T-HD was lowered. The ultrafine powder of the HDDR alloy became finer as T-HD decreased, with sizes in the range of 0.33 to 0.58 mu m.
