Abstract

The effect of Gd addition on the Glass Forming Ability (GFA), magnetic and thermal properties in (Fe0.72Mo0.04B0.24)(100-x)Gd-x (x = 4, 8) bulk metallic glasses were investigated. The examined amorphous alloys'. structural, thermal and magnetic properties were investigated by using X-ray diffraction (XRD), scanning electron mi-croscopy (SEM) differential scanning calorimeter (DSC) and vibrating sample magnetometer (VSM). The results show that molten (Fe0.72Mo0.04B0.24)(92)Gd-8 presents the fully amorphous structure and solidifies into two different Fe-rich and B-rich amorphous phases. The DSC curve shows that the (Fe0.72Mo0.04B0.24)(92)Gd-8 has supercooled liquid region (Delta T-x) of about 70 K and the saturation magnetization (J(s)) and coercivity (H-c) for as-cast bulk metallic glasses (BMGs) was 0.53 T and 223 A/m respectively.
