Fine-grained, heavy rare earth free Nd-Fe-B sintered magnets were prepared from He jet milled powders with an average particle size of 1.5µm by low temperature sintering at 920°C or 980°C. A coercivity of >1600kA/m was achieved for an average grain size of 1.68µm. Transmission electron microscopy showed that the distribution and composition of intergranular and grain boundary junction phases was...
