摘要(Abstract)：

用单辊快淬法和非晶晶化法制备Fe_(76)Co_6Zr_9B_9和Fe_(76)Co_6Zr_7Nb_2B_9非晶及纳米晶合金,用多种测试手段对两种合金的热曲线、显微组织及磁性能进行测试,研究添加原子数分数为2%的Nb对Fe_(76)Co_6Zr_9B_9合金结构和性能的影响。结果表明:不含Nb的Fe_(76)Co_6Zr_9B_9合金化产物含有亚稳相及α-Fe(Co)相,其矫顽力(H_c)较大,为半硬磁合金材料;添加Nb的Fe_(76)Co_6Zr_7Nb_2B_9合金晶化产物仅含有α-Fe(Co)相,为良好的软磁合金材料。添加原子数分数为2%的Nb抑制了合金化过程中亚稳相的析出,降低晶粒尺寸,提高了合金的比饱和磁化强度并明显降低合金的H_c。
