文摘

Three thermophysical properties: density, surface tension and viscosity of liquid binary Al-Zn and ternary Al-Li-Zn alloys have been investigated in this work, by means of the draining crucible method. Three Al-Li-Zn compositions corresponding to distinguished intermetallic phases, i.e. Al₅Li₃Zn, Al₃₅Li₃₂Zn₃₃ and AlLiZn₃, have been selected for investigation. Experimentally determined surface tension of ternaries has been compared to the modelled one, using the commonly known Butler's model and two sets of ternary interaction parameters given in the literature. Whereas, viscosity calculations for the ternary Al-Li-Zn alloys have been performed using three thermodynamics-based models, selected for their reliability, and confronted to the experimental data measured in this work. Both, measured and modelled surface tension decreased with increasing Li and Zn content, opposite to viscosities exhibiting an increase with Li and Zn content raise. Whereas measured densities of the investigated ternaries are decreasing with Li and Zn content growth in confrontation to the three respective Al-Zn binaries investigated in this work.
