摘要：

Effects of fluxing treatment on the glass forming ability and magnetic properties of Fe-based amorphous alloys prepared using industrial raw materials have been studied. The partially amorphous Fe76Si8P9C7 rod with the diameter of 1 mm was prepared by suction casting technique from the fluxed master alloy based on the industrial raw materials, while the alloy rod with the diameter of 1 mm obtained from the un-fluxed master alloy does not involve any amorphous phase. Melt spun ribbons prepared using the fluxed master exhibited lower the coercivity H (c) and power loss than those for ribbons prepared using the un-fluxed master alloy. These beneficial effects should be attributed to the purification of the master alloy through flux treatments. The results reveal that fluxing technique can play an important role in the development of Fe-based bulk metallic glasses using industrial raw materials with relatively low purities.
