基于团簇和胶粘原子模型的(Fe-Ni)-B-Y-Nb块体非晶合金
(Fe-Ni)-B-Y-Nb Bulk Metallic Glasses Based on the Model of Clusters and Glue Atoms
【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.
