Özet

The effect of Fe concentration on the glass forming ability (GFA) and magnetic properties in Co(40.2-x)Fe(20.1+x)Ni6.7B22.7Si5.3Nb5 (x=0-10) bulk metallic glasses were investigated. By suction casting method, the bulk metallic glasses with diameters up to 2 mm were produced. We try to find out which Fe concentration makes an influence on Co based system's magnetic properties and glass forming ability. The curves of thermal analysis, obtained using differential scanning calorimetry (DSC), show that the Co(40.2-x)Fe(20.1+x)Ni6.7B22.7Si5.3Nb5 (x=0-10) have a supercooled liquid region (Delta T-x) of about 44 K. The saturation magnetizations (J(s)) for as-cast BMG alloys were in the range of 0.62 T-0.81 T. (C) 2014 Elsevier B.V. All rights reserved.
