“…Calibration procedure was in detail described elsewhere. [22,25] The crucible used in these experiments had the same dimensions as the one used in our previous work. [22,32] The results presented in this work were measured in the temperature range from 773 K to 973 K (500°C to 700°C) with 50 K temperature step, and the mass of the measured alloys was between 0.5 and 0.7 kg.…”

“…Data for liquid lithium are more scarce than for Al and Zn elements and were taken from. [24] Thus, the aim of this work was to (a) measure the three physicochemical properties: density, surface tension, and viscosity of liquid Al-Li and Li-Zn alloys using Draining Crucible method [25][26][27] over a broad temperature range (from 773 K (500°C) to 973 K (700°C)) (b) calculate them by applying CFM formalism [15,16] (c) explain and understand the influence of short-range ordering on measured properties. Surface tension modeling was also performed using the Butler model [28] but viscosity by applying common known empirical models e.g., Kucharski, [29] Kaptay, [30] Kozlov et al [31] As final result we plan to obtain a complete database of physicochemical properties for liquid Al-Li and LiZn alloys.…”

Physicochemical properties like density, surface tension, and viscosity of liquid binary Al-Li and Li-Zn alloys have been measured using draining crucible method. The experimentally measured surface-tension values have been compared to theoretical results based either on the Butler model or the compound formation model assuming the existence of the most favored A 1 B 2 and A 2 B 3 clusters. Several models for viscosity calculation have been also applied and discussed in confrontation with measured data. Finally, the clustering effects in the liquid Al-Li and Li-Zn alloys have been examined using two microscopic functions, i.e., the concentration fluctuation function in the long-wavelength limit and the Warren-Cowley short-range order parameter.

A Comparison of Surface Tension, Viscosity, and Density of Sn and Sn–Ag Alloys Using Different Measurement Techniques

et al. 2011

View full text Add to dashboard Cite

This work is aimed at comparing several methods for the measurement of physical properties for molten Sn and Sn-Ag alloys, namely, surface tension, density, and viscosity. The method used for viscosity in this work is the modified capillary method. For surface tension and density, the data used for comparison were previously measured using the maximum bubble pressure method and the dilatometer technique, respectively, for four Sn-Ag alloys having (3.8, 32, 55, and 68) at% Ag. The results are compared with those obtained using a new method based on a fluid draining from a crucible under the influence of gravity, designated the Roach-Henein (RH) method. This new method enables the determination of these three physical properties in one set of measurements. Liquid Sn was used as well as two liquid Sn-Ag alloys having (3.8 and 34.6) at% Ag with the RH method. It was determined that the RH method may be used to simultaneously obtain surface tension, viscosity, and density and that the errors associated with these measurements were similar to those obtained using traditional and separate techniques. Comparisons of the measured viscosity and surface tension to those predicted using thermodynamic models will also be presented. Finally a comparison of mixing model predictions with the experimentally measured alloy surface tension and viscosity is also presented.

Physicochemical Properties of Sb, Sn, Zn, and Sb–Sn System

The physicochemical properties, viscosity, density, and surface tension, were measured using the discharge crucible method (DC) on five alloys of Sb-Sn. The performance of the DC method was demonstrated with measurements on pure metals Sb, Sn, Zn, and comparisons with the corresponding literature data. The results reported in this study are for Sb-Sn alloys containing (10, 20, 25, 50, and 75) at% of Sb at 550 K to 850 K. The results show that all the physicochemical properties decrease with decreasing temperature and increase with increasing Sb content in the alloy. The experimentally measured surface-tension values are compared with the Butler model. Several models for viscosity are compared and discussed.
