The generalized Bernal’s model for simple liquids is used as an approach to the structure of liquid and glassy metallic alloys with multiple components. The input parameters of the computer simulations are size distribution and composition of components. The atoms are approximated by hard spheres with the corresponding metallic radii. For each parameter set the maximum density of the system is searched. Additionally, size distribution and composition are varied in order to find systems with particularly high density. The results are discussed in terms of the so-called atomic size distribution plot introduced recently to characterize multicomponent bulk metallic glasses.
