- Abstract
- The effect of the replacement of Fe by Co or B on the thermal stability and soft magnetic properties of the Fe-based amorphous metallic ribbons with Fe(87-x-y)CoxTi7Zr6By (x = 10, 20% and y = 8, 10, 12%) produced by melt-spinning technique was investigated. For the melt-spun amorphous ribbons, the values of saturation magnetization and coercivity were observed to range from 107.00 to 152.38 emu/g and from 0.012 to 0.446 Oe, respectively. The thermal properties such as T-g, T-x, and Delta T-x were in the range of 796.7-809.6 K, 840.2-853.5 K, and 35.8-54.5 K, respectively. In the Fe-Co-Ti-Zr-B alloys, the Co substitution for Fe improved the soft magnetic properties but decreased the thermal stability. For magnetic properties, the coercivity (H-c) decreased and saturation magnetization (M-s) increased by the addition of Co. However, the supercooled liquid region (Delta T-x) decreased by the addition of Co. Meanwhile, the B substitution for Fe had no meaningful change on the thermal stability and soft magnetic properties. The amorphous ribbon of Fe59Co20Ti7Zr6B8 exhibited the best soft magnetic properties such as the low coercivity of 0.025 Oe and the high saturation magnetization of 152.38 emu/g.
