摘　　要：选择Fe-B-Y作为基础的三元合金系,选择最密堆的CN10 Archimedes八面体反棱柱Fe8B3作为基本团簇,Y作为胶粘原子,3at%Nb作为微合金化元素,形成四元合金:(Fe8B3-Y)97-Nb3,以不同含量的Ni替换Fe,形成五元合金:[(Fe1-xNix)8B3-Y]97-Nb3(x=6、14、22、30),用吸铸法制备出直径为2 mm的块体非晶合金。结果表明,在4个非晶合金成分中,当x=6时,合金具有最高的玻璃形成能力,同时具有最好的软磁性能:饱和磁感应强度为87.7 emu/g,矫顽力为7 Oe。The Fe-B-Y was selected as basic ternary alloy system, and using packing cluster archimedean octahedral anti-prism CN10 FesB3 as basic cluster, Y being glue atom, and then the system was minor-alloyed with 3at%Nb. The quaternary alloy was formed： （FesB3-Y）97-Nb3, finally Ni was added to partially substitute for Fe to improve the glass-forming abilities. Bulk metallic glasses with diameter of 2 mm are formed at compositions [（Fe1-xNix）8B3-Y]97-Nb3 （x=6, 14, 22, 30）. The casting experiments reveal that the good glass-forming ability occurs at [（Fe8B3-Y）97-Nb3 composition. The alloy has good soft magnetic properties. The optimum saturation magnetization reaches 87.7 emu/g, and coercivity is 7Oe.
