Abstract
(Fe72Mo4B24)100−xDyx (x = 4–7) bulk metallic glasses (BMGs) cylindrical rods with diameters up to 3 mm and a length of 30 mm were prepared by copper mold casting. The influence of Dy content on the glass forming ability (GFA) of Fe–Mo–B–Dy alloy system was investigated. With the increase of Dy content, the supercooled liquid region ΔTx (=Tx − Tg) increased from 75 K for x = 4 to 91 K for x = 6. The (Fe72Mo4B24)94Dy6 alloy possessed the largest ΔTx (91 K), indicating the best GFA among the investigated alloys. The BMGs exhibited high compressive fracture strength up to 3071 MPa and micro-Vickers hardness up to 1130 kg/mm2. The appreciable magnetic properties of the alloy system were obtained as well.
