摘要

•Atom-by-atom growth simulations of Cu-Zr-Al performed in a wide range of Al contents.•Simulations predict homogeneity, densification, short-range order, medium-range order.•Reactive magnetron sputtering of Cu-Zr-Hf-Al performed in a wide range of Al contents.•Measured hardness, Young's modulus, glass transition T and crystallization T.•There are icosahedral clusters around Cu and Al & supraicosahedral clusters around Zr.
