Abstract: Two alloys were atomized by 8. OMPa Argon gas. Optical microstructure observation and X-ray diffraction analysis authenticated that the obtained powder is mainly composed of a tetragonal Nd₂Fe₁₄B phase. The tHe value of the powder is relatively higher compared with that of the powder from pulverizing as-cast Nd-Fe-B alloy bulk,and gives rises after annealing at 973K for an hour, The iHc value varies with the rang of particle diameter, the more finer the powder particles are, the more higher the tHe value is. The initial magnetization behavion of the powder is analogous to that of conventional as-cast magnets.
