Abstract

Cylindrical cast rods and melt-spun ribbons of Nd60Fe30B10 and two Nd67Fe26B7 and Nd10Fe73B17 eutectic alloys were prepared by copper mold casting and melt spinning. Coercivity of the as-cast Nd60Fe30B10 rod was 434 kA/m. Coercivity of the cast rod was increased to 1285.6 kA/m after annealing due to the formation of Nd2Fe14B phase. The as-cast eutectic Nd67Fe26B7 rod, which is partially amorphous, exhibited coercivity value identical to that of the alloy Nd60Fe30B10 (∼430 kA/m). On the other hand, eutectic Nd10Fe73B17 shows better glass forming ability, but lower coercivity (∼100 kA/m).
