Abstract

Dependence of magnetic properties and mkrostructure m boron additions for nitrogenated (Sm,ZrXFe,Co)₉ alloys fabricated by rapidly quenching was investigated. The condition for getting high (BH)_maxXti high_iH_c is to produce an amorphous phase in the rapidly quenched sample because it leads to the precipitation of uniform and fine grains by the annealing above their crystallization temperature. Hie rote of boron is to form the amorphous phase easily by rapidly quenching. High (BH)_max of about 20MGOe with high ft of 9. 6kOe was obtained for nttrogenated (Sm_{0. 7}Zb_{0. 3})(Fe₀₉₅Oa₀₀₅)₉Ai- High (BH)_max of 13. 0MGOe was also attained as an Isotropie resin bonded magnet with density of 6. 2g/cm³.
