摘　　要：基于原生产设备所用的单辊激冷技术，在放热还原气氛中制备出宽40mm、厚25μm的Fe78Si9B13非晶合金带材。利用金相显微镜（OM）、X射线衍射仪（XRD）和磁性测量装置对所得Fe78Si9813非晶合金带材的表面质量、物相和磁性能进行分析表征，结果表明，对比原设备空气中所制备的带材，放热还原气氛所浇注成型的带材贴辊面气孔较小且分布均匀，软磁性能也有所改善。Based on the original production facility, which is the single-roller spinning technology, Fe78Si9B13 amorphous alloy strip with width of 40mm and thickness of 25gm in the exothermic reducing atmosphere is prepared. And the strips areinvestigated by the OM,XRD and testing magnetic facility. The results are as follows： strip casted in an exothermic reducing atmosphere is of better surface quality and more excellent soft-magnetic property.
