The influence of Cr, Mo and Mn on structural changes and magnetic properties of Co75,5Fe4,5Si6B14 amorphous alloy

Abstract

The annealing of amorphous alloys, that is needed in order to improve their properties, is connected with various changes of structure and properties. The understanding of such changes is interesting both from fundamental and applied views. On that reason the influence of Mo and Cr admixtures on the main structure parameters and physical and chemical properties has been studied. For investigation of amorphous alloys the X-ray-diffraction, differential scanning calorimetry, magnetic susceptibility and High-resolution microscopy methods were used. Experimental data allowed us to estimate the changes in crystallization kinetics and to calculate the activation energies. These results were analyzed conjointly with data on X-ray diffraction and magnetic measurements. © 2008 IOP Publishing Ltd.
