Abstract
Abstract
The effects of additions of Co and Ni to the FeNbBCu alloys on the glass forming ability (GFA), soft magnetic properties and electrical resistivity of Fe-based amorphous alloys were studied by means of X-ray diffraction, differential scanning calorimetry, vibrating sample magnetometry and four-probe testing. The Fe80–x–y

m ≥ 0.539. They also show excellent soft magnetic properties with high saturation magnetization of 93– 101 emu g–1 and low coercivity of 0.04 –2.37 Oe. The electrical resistivity of these alloys ranges from 121 μΩ cm to 163 μΩ cm. The newly developed FeNbBCu-CoNi glassy alloys not only possess good GFA and high thermal stability, but also have excellent magnetic properties, high electrical resistivity and low cost. With such promising properties, these alloys have potential for industrial applications.
