## Description

- description: 'The atomic structure of medium-range order in metallic glasses is
    investigated by using molecular dynamics (MD) simulations. Glass formation processes
    were simulated by rapid cooling from liquid phases of a model binary alloy system
    of different-sized elements. Two types of short-range order of atomic clusters
    with the five-fold symmetry are found in glassy phases: icosahedral clusters (I-clusters)
    and Frank–Kasper clusters (i.e., Z14, Z15, and Z16 clusters (Z-clusters)). Both
    types of clusters are observed even in liquid phases and the population of them
    goes up as the temperature goes down. A considerable atomic size difference between
    alloying elements would enhance the formation of both the I- and Z-clusters. In
    glassy phases, the I- and Z-clusters are mutually connected to form a complicated
    network, and the network structure becomes denser as the structural relaxation
    goes on. In the network, the medium-range order is mainly constructed by the volume
    sharing type connection between I- and Z-clusters. Following Nelson’s disclination
    theory, the network structure can be understood as a random network of Z-clusters,
    which is complimentarily surrounded by another type of network formed by I-clusters.'
