Abstract

The effect of the addition of P and Cu to Fe₈₅Nb₆B₉ alloy on an as-quenched structure and soft magnetic properties in a nanocrystallized state has been investigated. The Fe₈₅Nb₆B₉ alloy melt-spun in air has an as-quenched structure of an amorphous phase and α-Fe grains with 20-45 nm in size. The coarse grains should still remain in the nanocrystallized structure, which deteriorates the soft magnetic properties. The simultaneous addition of 1 at.% P and 0.1 at.% Cu to the Fe₈₅Nb₆B₉ alloy decreases the α-Fe grain size to nanoscale in an as-quenched state, and realizes a uniform crystallized structure with high saturation induction of 1.61 T as well as high permeability of 41,000.
