Formation, Crystallization Behavior, and Soft Magnetic Properties of FeCSiBP Bulk Metallic Glass Fabricated Using Industrial Raw Materials

摘要

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 Fe_(77.3)C_(5.9)Si_(3.3)B_(4.8)P_(8.7) alloy. The crystallization behavior and its effects on the soft magnetic properties of the Fe_(77.3)C_(5.9)Si_(3.3)B_(4.8)P_(8.7) 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.
