N2 - Ultra-fine amorphous powders in (Fe, Co, Ni)-B binary and ternary systems were produced by the chemical reduction method. The powders have a spherical shape with diameters ranging from 5 to 50 nm. The reaction consists mainly of the process of producing Me2B and Me(Me = Fe, Co, Ni. Fully dense bulks of the ultra-fine amorphous (Fe, Co, Ni)-B powders were prepared by hot-pressing at temperatures below the crystallization temperature. Their densities are almost equal to those of the corresponding arc-melted powders. The hardness values of the hot-pressed compacts are considerably lower than those of the melt-spun amorphous ribbons with the same compositions.
