The as-quenched and nanocrystallization structures of Nb-poor Fe-Nb-B(-P-Cu) alloys melt spun in air were investigated. The Nb-poor Fe85Nb6B9 alloy has the as-quenched structure composed of an amorphous phase and large α-Fe grains with 20-45 nm size. The results show that precursor to the uniform nanostructure with high permeability was not always a fully amorphous phase and there was a possibility to realize to materials with higher saturation induction and with higher Fe contents.
