The effects of Si and/or P addition in amorphous Fe_86+x(B_12.5M_0.5Cu_0.4Hf_0.6)_14-x (M = P, Si; x = 0.2, 0.4 and 0.6) and Fe_86+a(B₁₂N₁Cu_0.4Hf_0.6)_14-a (N = PSi; P/Si = 3/1, 1/1 and 1/3; a = 0.2, 0.4 and 0.6) alloys on the amorphous forming ability, thermal stability and soft magnetic properties were investigated. The results indicated that Si had stronger effect on the AFA than that of P element. The increase of Si/P ratio enhanced the AFA. Both Si and/or P addition decreased the onset temperature of the first crystallization, meanwhile the decreased Si/P ratio resulted in higher thermal stability of the second crystallization. After optimal heat treatments, B_s and H_c of the Fe_86.4(B_12.5Si_0.5Cu_0.4Hf_0.6)_13.6 crystallized ribbons reached to 1.95 T and 3.1 A/m, that of the crystallized Fe_86.4(B₁₂P_0.25Si_0.75Cu_0.4Hf_0.6)_13.6 ribbons were 1.98 T and 2.1 A/m, respectively. These materials are potentially applied in the high magnetic flux transaction fields.

非晶态Fe _{86+ x}（B _12.5 M _0.5 Cu _0.4 Hf _0.6）_{14- x}（M = P，Si; x  = _0.2、0.4和0.6）和Fe _{86+ a}（B中添加Si和/或P的影响₁₂ N ₁ Cu _0.4 Hf _0.6）_{14- a}（N = PSi; P / Si = 3/1，1/1 and 1/3; a  = 0.2，0.4 and 0.6）合金的非晶形成能力，热稳定性和研究了软磁性能。结果表明，硅对AFA的作用更强。比P元素 Si / P比的增加提高了AFA。Si和/或P的添加均降低了第一结晶的开始温度，同时降低的Si / P比导致第二结晶的更高的热稳定性。经过最佳热处理后，Fe _86.4（B _12.5 Si _0.5 Cu _0.4 Hf _0.6）_13.6结晶带的B _s和H _c达到1.95 T和3.1 A / m，而Fe _86.4（B ₁₂ P _0.25 Si _0.75铜_0.4 Hf_0.6）_13.6色带分别为1.98 T和2.1 A / m。这些材料潜在地应用于高磁通量交易领域。
