Using molecular dynamics simulations with embedded atom model potential, we study
structural evolution of Cu 64.5 Zr 35.5 alloy during the cooling in a wide range of cooling
rates γ∈(1.5⋅ 10 9, 10 13) K/s. Investigating short-and medium-range orders, we show that
the structure of Cu 64.5 Zr 35.5 metallic glass essentially depends on cooling rate. In
particular, a decrease of the cooling rate leads to an increase of abundances of both the
icosahedral-like clusters and Frank-Kasper Z16 polyhedra. The amounts of these clusters in …
