本文叙述了用单辊法制造的(Fe、Ni)-(P、B)和(Fe、Co)-(Si、B)系的几种非晶态软磁合金带.尺寸为30～50μm厚,宽30mm.经x光、电子衍射及透射电镜检验,证明了非晶态结构.通过对合金成份的优选和磁场热处理制度的实验研究,得到了Fe Co_(31.8)Si_(8.4)B_(2.5)(wt%)非晶态合金带,经370℃、20Oe、保温30分钟的真空热处理之后,磁性能为B_s=8500G,H_o=0.03O_e,μ_m=21000;Fe_(44)Ni_(46)P_8B_2(wt%)非晶态合金带经310℃,20Oe,保温30分钟的真空热处理之后,磁性能为B_s=8500G,
In this paper, several amorphous soft magnetic alloy ribbons of (Fe, Ni) - (P, B) and (Fe, Co) - (Si, B) , 30mm wide.An amorphous structure was confirmed by x-ray, electron diffraction and transmission electron microscopy.The Fe Co 31.8 Si 8.4 B 2.5 was obtained by optimizing the alloy composition and the magnetic field heat treatment system. ) (wt%) amorphous alloy ribbons, the magnetic properties of which are B_s = 8500G, H_o = 0.03O_e and μ_m = 21000 after vacuum heat treatment at 370 ℃ and 20Oe for 30 minutes. Fe_ (44) Ni_ (46) P_8B_2 (wt%) After the amorphous alloy strip was vacuum heat-treated at 310 ° C and 20 Oe for 30 minutes, the magnetic property was B_s = 8500G,
