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

The present study examines the effect of various inhibitors on the structure and magnetic properties of nanocrystalline Fe73.5Cu1M3Si13.5B9 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.
