Viscosity Measurements of Molten Sn–Ag–Cu Alloy Using an Oscillating Crucible Viscometer
Abstract
equation, temperature and composition dependenciesIn this study, the viscosities of molten pure Sn, a Sn-Pb eutectic alloy, and Sn-Ag-Cu alloys, whose properties such as liquidus temperature were similar, were measured using an oscillating crucible viscometer over a temperature range of 483-668 K.For the Sn-Ag-Cu alloys, measurements were conducted on Sn-0.8Cu,Sn-1Ag-0.7Cu,and Sn-4Ag-0.5Cualloys (mass%) with various Ag contents.The viscosities of molten pure Sn obtained using a viscometer ranged from 1.2 to 1.6 mPa•s, which were in good agreement with those reported in the literature.Additionally, the viscosity of the molten Sn-Pb alloy closely matched the values reported by T.
