This article selected the composition of the Fe73NbxAl5-xGe2 P10 C6B4 (x = 0, 1,3,5, atomic percent) of the alloy system. The strips with width of 5 mm and thickness were prepared by single roller quenching method. The thermal stability, amorphous structure and magnetic properties of the alloy were studied by means of DSC, XRD and Faraday magnetic balance, static magnetic measuring instrument. It is found that the supercooled liquid region ΔTx of Fe73NbxAl5-xGe2 P10 C6B4 alloy containing 1% (atomic) Nb is the broadest, reaching 6 6K, and can be completely amorphous with a thickness greater than 10 μm. The entire alloy system has a high saturation magnetization σs. After annealing at 973K for 90 s, the σs and Hc of the alloys rapidly increase due to the precipitation of α Fe and other crystalline phases
