Viscosity of aluminum–copper melts

The results of measuring the density of copper–aluminum melts obtained by Kurochkin et al. by the penetrating γ-ray technique are used to correct the results of viscosimetric experiments with melts of this system performed earlier by Konstantinova, who had no data on the density at that time and used the values of density obtained by a linear extrapolation between the densities of the pure components. This led to an error between the published values of viscosity, reaching 20% in some cases. The refined calculation results for the viscosity taking into account new data on the density of the copper–aluminum melts are recommended for use as reference data.
