Description
The effects of Fe content on the thermal, magnetic, and mechanical properties of a Co72B19.2Si4.8Mo4 alloy were studied. Amorphous soft magnetic alloys of (Co1−xFex)72 B19.2Si4.8Mo4 (0 ≤ x ≤ 1) with 3-mm widths and 27 - 30 μm thicknesses were obtained by using the melt spinning technique. The crystallization temperature (Tx) for each alloy was measured by using differential scanning calorimetry (DSC). All ribbons were identified as fully amorphous by using X-ray diffraction (XRD). The magnetic properties of the amorphous ribbons were measured by using a vibrating sample magnetometer (VSM). The Fe-only ribbon (x = 1) showed the highest saturation magnetization of 1.15 T in these alloys. Also, the nano-hardness (Hnanoindentation), and Young's modulus (E) were evaluated by using nano-indentation experiments, and Co21.6Fe50.4B19.2Si4.8Mo4 (x = 0.7) show a nano-hardness (Hnanoindentation) of 18.92 GPa.
