- Abstract
Hard magnetic properties of nitrogen intentitially modified NdMxFe12-xNy compounds and Fe3B-based ultra-fine crytaline Nd-FeCo-T-B alloys of low Nd content of 3 to 5 studied. Thenitrogen-modified compounds have been prepared via the rapid solidification route and the mechanical allowing route both follwed by gas nitrogenation using N2. The Fe3B-based materials have been prepared by means of rapid solidification and crystallization treatment. The latter materials appears promising as the base material for high remanence, easy-to-manetize bonded magnets small temperature coefficients of remanence. Typical magnetic properties of compaction isotropic isotropic bonded magnets produced from this material from this material are Br = 0.80 T, Hcj = 350 kA/m, and (BH)max = 60.5 kj/m3.
