| 摘 要： | 应用团簇+胶粘原子模型在三元Fe-B-Y合金系中设计三元合金成分,选择最密堆的CN10Archimedes八面体反棱柱Fe8B3作为基本团簇,Y为胶粘原子。在此基础上添加3at%Nb作为微合金化元素形成四元合金。以适量的Ni替换Fe,形成五元合金[(Fe100-xNix)8B3-Y]97-Nb3。结果表明,当Ni的含量小于30at%时,均可形成直径为2mm的块体非晶合金,其中,合金[(Fe94Ni6)8B3-Y]97-Nb3具有最大的Tg、Tx和Trg值,分别为:884K、972K和0.634。 |

| Abstract: | Using the model of cluster + glue atom, the ternary bulk metallic glasses (BMG) in Fe-B-Y system was designed, choosing the close-packed Archimedes octahedral antiprism CN-10 Fe8B3 as basic cluster and Y as glue atom. 3at%Nb was added as minor alloying element to form quaternary BMG. Ni was used to substitute for Fe, and a quinary BMG, [(Fe100-xNix)8B3-Y]97-Nb3, was formed. Results show that when Ni is less than 30at% the BMG with diameter of 2 mm can be obtained and the alloy [(Fe94Ni6)8B3-Y]97-Nb3 has the biggest Tg, Tx and Trg which are 884 K, 972 K and 0.634, respectively. |
