Summary
The viscosity of Zn-Al alloys melts, with industrial interest, was measured for temperatures between 693 K and 915 K, with an oscillating cup viscometer, and estimated expanded uncertainties between 3 and 5%, depending on the alloy. The influence of minor components, such as Si, Mg and Ce + La on the viscosity of the alloys is discussed. An increase in the amount of Mg triggers complex melt/solidification processes while addition of Ce and La renders alloys viscosity almost temperature independent. Furthermore, increases in Al and Si contents decrease melts viscosity and lead to an Arrhenius type behavior. This paper complements a previous study describing the viscosity of Zn-Al alloys with quasi-eutectic compositions.
