Abstract
Formation of pseudo-binary Fe-C-Si-B-P bulk metallic glasses (BMGs) with good glass-forming ability (GFA) and soft magnetic properties prepared using industrial pig-iron and P-Fe alloys as raw materials was investigated. It was found that the GFA could be enhanced by tuning the content of carbon, and fully glassy rods with a maximum diameter of 2 mm were obtained in the Fe77.3C5.9Si3.3B4.8P8.7 alloy. The crystallization behavior and its effects on the soft magnetic properties of the Fe77.3C5.9Si3.3B4.8P8.7 alloy were analyzed. The superior magnetic properties, coupled with large GFA and low cost of raw materials, make the current Fe-based BMGs promising for potential applications in electric industries.
