章節(jié)摘錄

版權(quán)頁：   插圖：   Ab initio molecular dynamics(AIMD)calculations were performed on the atomic configuration of Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulkmetallic glass.The local structures were characterized in terms of structure factors(SF),pair correlation functions(PCF),coordinatenumbers,bond pairs and Voronoi polyhedra.The glass transition temperature,generalized PCF and SF predicated by AIMD are ingood agreement with the experimental data.Icosahedral short—range orders（ISRO）are found to be the most dominant,in view ofthe presence of the majority of bond pairs with l551,1541 and 1431,and Voronoi polyhedra with〈0,3,6,1〉,〈0,2,8,1〉,〈0,0,12,0〉and〈0,2,8,4〉，Icosahedral medium range orders(IMROs)are formed from icosahedra Via the linkage of vertex-，edge-，face-and inter-cross-shared atoms.The glass structure on the nanometer scale is accumulated by polyhedra through an efficient packing mode.It issuggested that the extraordinary glass-forming ability of this alloy is essentially attributable to the formation of ISRO and IMRO,and the dense packing of atoms.
