Effect of Zr and Nb on the Electrical and Magnetic Properties of the Fe-Zr-Nb-B-Cu Alloy

The present study, aims to investigate the effect of minor Zr and Nb alloying on soft magnetic and electrical properties of Fe₈₆ (Zr_x Nb_1-x )7B₆ Cu₁ (x=1, 0.75, 0.5, 0.25) alloys. The investigated alloys were prepared through the melt spinning process. Within the examined compositional range (Nb up to 5.25 at%, respectively), the soft magnetic properties and electrical resistivity of the alloys continuously increase with increasing Nb content. However increasing the Nb content further decreases such properties. We could confirm the influence of ratio of Zr and Nb on grain growth and crystallization fraction during crystallization by using the soft magnetic properties and electrical properties.
