Abstract
The physicochemical properties, viscosity, density, and surface tension, were measured using the discharge crucible method (DC) on a wide range of pure melts and alloys and for AZ91D in two gas atmospheres. The DC method was confirmed on pure metals, Sb, Sn, Zn, and compared with corresponding literature data. Results are also reported for Sn–Sb alloys containing (10, 20, 25, 50, and 75) at% of Sb at 550 K to 850 K, for Sn–Ag alloys containing (3.8, 32, 55, and 68) at% Ag, for commercially pure Al, and for an AZ91D Mg alloy under an argon atmosphere. The properties for AZ91D were also measured under an atmosphere of air containing 2 % $$\hbox {SF}_{6}$$ . The results are compared with published data on all alloys. The experimentally measured surface-tension values are compared with the Butler model. Several models are compared and discussed for the viscosity measurements.
