摘要：

Microstructure, phase constitution and temperature-dependent magnetic properties are examined for two size fractions of as-quenched RE-Nd-B-based powder produced by inert gas atomization for possible use as isotropic bonded magnet precursors, The atomized powders consist of the phase (Nd,Dy)(2)Fe14B with minute amounts of RE(2)O(3) and gamma-Fe2O3. Evidence of compositional segregation with particle size is seen, Room-temperature magnetic properties are H-ci=12kOe and B-R=5.4 kG for the 10-20 mu m portion, H-ci=1.8 kOe and B-R=3 kG for the 100-150 mu m portion.
