Abstract

We address a relationship between properties of liquid and solid states by comparing structural characteristics and viscosity in Al–Cu–Fe and Al–Cu–Ni melts. The former system forms an equilibrium quasicrystalline phase but the latter does not. We show that the concentration behavior of the viscosity, melting temperature and characteristics of the chemical short-range order correlate with each other. The main structural differences between the melts are related to the peculiarities of their electronic structure, which is the same for liquid and solid states near the melting temperature.
