New Fe-metalloids based amorphous alloys with a wide supercooled liquid region of over 50 K have been synthesized by the addition of P and/or C and subsequent optimization of metalloid composition. These alloys can be form a bulk rod specimen with a diameter of up to 3.0mm and exhibit high magnetic flux density of above 1.5T as well as extremely low coercivity. Furthermore the Fe-Si-B-P-Cu bulk amorphous alloy shows both high fracture strength of above 3GPa and high plastic deformability of 4%. On a development of the soft magnetic core, a spark plasma sintered Fe-Si-B-P bulk amorphous core performs lower magnetic core loss than that of typical silicon steel in the high frequency region.

通过添加P和/或C以及随后的类金属成分的优化，合成了具有超过50 K的宽过冷液相区的新型Fe-类金属基非晶合金。这些合金可制成直径达3.0mm的块状棒形试样，具有1.5T以上的高磁通密度和极低的矫顽力。此外，Fe-Si-B-P-Cu大块非晶合金具有3GPa以上的断裂强度和4%的塑性变形能力。在软磁芯的开发中，放电等离子体烧结的Fe-Si-B-P大块非晶磁芯在高频区域中表现出比典型的硅钢更低的磁芯损耗。
