Relation of Structure, Composition and Glass Forming Ability in Zr-Cu Binary Amorphous Alloys

Relation of Structure, Composition and Glass Forming Ability in Zr-Cu Binary Amorphous Alloys

Molecular dynamics simulation was used to simulate Zr-Cu binary system, in which the relationship between structure, composition and glass forming ability was study. Atomic local structures were analyzed from view of chemical and topological short range order. Reduction fraction of full icosahedra (...
