Notes:
Two methods were used to prepare NdFeB alloy particles for sintered magnets: the reduction-diffusion (R/D) method and the melting and casting (M/C) method. In both materials, the Nd-rich phase appears along grain boundaries, but the grain size of the R/D alloy is much smaller than that of the M/C alloy. The shape of the R/D powder particles is more rounded than that of the M/C powder, and the size distribution of the R/D powder is more uniform than that of the M/C powder. These alloys were jet-milled into powders of 3.3 and 3.6 μm diameter, respectively, and were processed into sintered magnets. The large Nd-rich phase are more numerous in the M/C than in the R/D sintered magnet.
