Abstract

The soft magnetic properties of the nanocrystalline Fe-Zr-Nb-B alloys, which are mixed Fe-Zr-B alloy with negative magnetostricton and Fe-Nb-B alloy with positive one, have been investigated. The magnetostricton and the grain size of the Fe-Zr-Nb-B alloys show intermediate values between those of the Fe-Zr-B and Fe-Nb-B alloys. The soft magnetic properties are strongly affected by Zr + Nb amount and Zr/Nb ratio. The best soft magnetic properties have been obtained for the Fe_85.5Zr₂Nb₄B_8.5 alloy. The alloy shows a high permeability of 60 000 at 1 kHz, a high saturation magnetic flux density of 1.64 T and zero-magnetostriction, simultaneously. The alloy also exhibits a very low core loss of 0.09 W/kg at 1.4 T and 50 Hz, which is extremely lower than that of Fe-Si-B amorphous, and good thermal stability of the core loss. The nanocrystalline Fe-Zr-Nb-B alloy is therefore suitable for a core material for pole transformers.
