The viscosity re-assessment of the Cu–X (X = Ag, Al, Sn, Mg) and Ag–X (X = Sn, Sb, In, Au) liquid alloys

The viscosity of the eight binary systems (Cu–X ([Formula: see text], Al, Sn, Mg) system and Ag–X ([Formula: see text], Sb, In, Au)) was re-assessed, employing a new CALPHAD-type equation model proposed in our previous work. The calculated viscosities of the binary alloys were compared with the experimental data. It was found that this CALPHAD-type equation is very effective in fitting with the experimental data. Therefore, this work proves the validity of our new CALPHAD-type equation model for accurate viscosity predictions in alloys with varying component compositions.
