The microstructure and the magnetic properties of melt-spun Fe-Nb-B alloy ribbons were examined. High permeability at 1 kHz above 20,000 as well as saturation flux density Bs of about 1.5 T were obtained in the compositional range of 5.5 to 7.5 at% Nb and 8 to 12 at% B for nanocrystalline bcc Fe-Nb-B alloy ribbons annealed for 3.6 ks at 923 K. Soft magnetic properties substantially depend on the annealed structure which does not essentially depend on as-quenched structure for Fe[sub 84]Nb[sub 7]B[sub 9] alloy ribbons.
