Abstract
Influence of Si and Co substitution for Fe in rapidly quenched Fe86B14-type alloy (metallic ribbons form) on the crystallization temperature, crystal structure and magnetic properties are reported for three different metallic glasses: Fe86B14, Fe84Si2B14, and Fe80Co4Si2B14. At first, the onset temperatures of crystallization process were determined for both bcc-Fe (primary crystallization) and bct-Fe3B phase types (secondary crystallization) by calorimetric measurements with use of 10 ◦C/min heating rate. On the basis of obtained results, the conventional heat treatment process (with heating rate 10 ◦C/min and subsequent isothermal annealing) for wound toroidal cores has been optimized in order to obtain best soft magnetic properties (minimum value of coercivity Hc and magnetic core loss Ps) at frequency f = 50 Hz. For the optimal annealed samples the complex magnetic permeability (µ0, µ00) was measured, in the frequency range 104–108 Hz. Finally, the stage of the crystallization process was identified by the use of X-ray diffraction (XRD) method and the transmission electron microscopy (TEM) observations. © 2020 Polish Academy of Sciences.
