- W2333953893 abstract "通过单辊快淬法制备了Fe-B-C-Cu非晶态合金，并利用等温退火法对其进行晶化热处理制得纳米晶。用DSC、XRD、TEM、VSM、交直流B-H仪等对其微观结构及软磁性能进行了研究。结果表明：Cu的添加作为α-Fe形核点的作用明显，有效地促进了具有纳米级尺寸的单相α-Fe的析出，Fe84-xB10C6Cux系纳米晶合金的矫顽力随Cu含量的增加而先降低后增加，饱和磁感应强度则由于α-Fe的析出而呈增大的趋势。当Cu原子百分含量为1时，该系合金具有最佳的软磁性能，如高饱和磁感应强度Bs= 1.78 T，低矫顽力Hc= 5.1 A/m，低铁损P10/50= 0.34 W/kg。 In this study, the microstructures and soft magnetic properties of Fe-B-C-Cu alloys prepared by annealing the melt-spun ribbons have been investigated by DSC, XRD, TEM, VSM, AC and DC B-H tracer measurement. The results show that inFe84-xB10C6Cuxalloy system, the addition of Cu element takes great effect on the precipitation of α-Fe, coercivity (Hc) decreases with increasing x and exhibits a minimum at x=1.0, then Hc increases. And magnetic flux density (Bs) shows an increasing tendency due to the precipitation of α-Fe. When x=1.0, the alloy exhibits excellent magnetic properties with a high Bs of 1.78 T, low Hc of 5.1 A/m and low core loss of 0.34 W/kg at 1.0 T and 50 Hz." @default.
