摘　　要：采用XRD、DSC、SEM、TEM和VSM等检测方法研究了Fe(73.65-x)Ni1Al5Ga2PxB9.6Si3C5.75(x=6.65、7.65、8.65、9.65)系列合金的微观结构、玻璃形成能力及磁性能。实验结果表明,当x=8.65时,样品为非晶结构,并深入分析了此时结构中的原子团簇结构;当x=7.65时,合金为在非晶基体上析出的纳米晶结构;当x=6.65时,在非晶基体上出现了大量的晶态相复合组织。热力学分析显示,用参数γ能更合理地表征合金的玻璃形成能力,为C1>C2>A4。当P含量为7.65%(原子分数)时合金具有较好的软磁性能,其矫顽力为6.0Oe,饱和磁化强度为149.4emu/g。The effects of P on microstructure, glass forming ability and magnetic properties of Fe（73.65-x）Ni1Al5Ga2PxB9.6Si3C5.75（x=6. 65,7. 65,8. 65,9. 65） series alloys are investigated by XRD, DSC, SEM, TEM and VSM. The experiment results show that it is amorphous structure when x is 8. 65. The structure of atom clusters is analyzed. Nano-scale structure appears on amorphous when x is 7. 65 ; when x is 6.65, it is the composite structure of amorphous and nano-crystals. Thermodynamics analysis shows that parameter y can be used to indicate glass forming ability reasonably： C1〉C2〉A4. Amorphous alloy has a better soft magnetic properties with the content of 7. 65% P. The coercive force （Hc） is 6. 0Oe and the saturation magnetization（Ms） is 149. 4emu/g.
