The Effect of Inhibitors on the Structure and Magnetic Properties of Nanocrystalline Soft Magnetic Alloys

Abstract

The present study examines the effect of various inhibitors on the structure and magnetic properties of nanocrystalline Fe_73.5Cu₁M₃Si_13.5B₉ alloys, where M = Nb, W, Mo, V, Cr, or a combination of these elements. The introduction of inhibitors with higher solubilities in α-Fe results in an increase in the lattice parameter of the Fe₃Si phase and induces a more marked drop in the initial permeability of the nanocrystalline alloy. A combination of several inhibitor elements is used and this allows an increase in the crystallization temperature and optimization of the core thermal treatment regime.
