“…It is well known that low temperature annealing will reduce the Hc as a result of the internal stress relief reducing magnetoelastic anisotropy and re orientation of the easy magnetization direction (Dai et al, 2017). Important thermodynamic parameter primary crystallization corresponds to the precipitation of an ordered bcc α-Fe(Si) solid solution embedded in an amorphous phase and secondary Fe2B phase for effect on the crystallization process (Sikder et al, 1999;Soltani et al, 2017;Öztürk et al, 2019). The Crystallites gran size and the percentage of Si content with heating temperature of such novel materials exhibits interesting properties including physical, chemical, magnetic and electrical properties compare to conventional coarse-grained counterparts.…”

Fe82Si8B10 amorphous ribbon which containing 82% of Fe and 18% of B and Si were prepared using rapid solidification technique. The samples were constantly annealed for 1 hour in the temperature range of 350°C-600°C. X-ray diffraction analysis (XRD) displays a large peak which is the diffusion hallow suggesting the amorphousity in its origin and formation of crystalline phase with the increment of annealing temperature at 450oC. The magnetic ordering of the ribbon is determined as temperature functions by both AC and DC magnetization. At 450°C, the saturation magnetization (Ms) was found 143 emu/gm and with better value of real part of initial permeability at 450°C as well as better relative quality factor (RQF) was observed at the same temperature. The results are explained as due to higher heating rates than this Si diffuse in amorphous and lost the soft magnetic properties. Journal of Engineering Science 13(1), 2022, 1-8
