In this work the dynamic viscosity of liquid metal alloys of eutectic composition is investigated. In particular a semi empirical equation, previously proposed for some pure metals, is now tested to estimate the viscosity of liquid metal alloys. Analysis is limited by three materials that have been evaluated by a recent care ful analysis by Assael and co workers: Al-Si, Pb-Bi, and Pb-Sn of eutectic composition. The equation pro posed shows a satisfactory agreement with the accredited data available in literature.

Viscosity is a crucial parameter affecting the fluidity of metal melts, which directly influences the founding properties of Al alloys. However, obtaining viscosity measurement data is difficult for metal melts, and the viscosity prediction for ternary and multicomponent alloys would provide the significant data for the selection of process parameters. This study compares the applicability of the Hirai model, SDS model, and R‐K function for viscosity calculations in the sub‐binary systems of Al–Si–Mg–Fe alloys. R‐K function shows the best agreement with experimental data. However, the SDS model shows lower relative error than Hirai model, which would play an important role in those systems lacking experimental data to predict the viscosities. Ultimately, a database capable of predicting viscosity values for the entire composition and temperature range of the Al–Si–Mg–Fe system is established using the CALPHAD method. Viscosity parameters for Al–Si, Al–Mg, Al–Fe, Mg–Si, and Mg–Fe are evaluated and optimized through the R‐K derivation, corroborated with existing experimental data. Using the R‐K function, successful extrapolation and prediction of viscosity for the Al–Si–Mg–Fe ternary and quaternary systems are achieved, with a mean square error between predicted and experimental values of only 0.7%, demonstrating the successful application of the Al–Si–Mg–Fe database for viscosity prediction.

The available experimental data for the density, thermal conductivity, and viscosity of liquid titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, and tungsten have been critically examined with the intention of establishing reference correlations. All experimental data have been categorized into primary and secondary data according to the quality of measurement, the technique employed, and the presentation of the data, as specified by a series of criteria. In the case of the density, new reference correlations are proposed for liquid titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, and tungsten, characterized by an expanded uncertainty (95 %) of 2.0 %, 2.1 %, 1.9 %, 2.2 %, 2.4 %, 2.6 %, 3.2 %, 2.1 %, and 4.1 %, respectively. The thermal conductivity reference correlations for the aforementioned liquid metals, except liquid chromium, are characterized by an expanded uncertainty (95 %) of 14.3 %, 8.4 %, 6.1 %, 11.4 %, 7.6 %, 4.0 %, 4.6 %, and 5.1 %, respectively. Finally, in the case of the viscosity, a review of the available literature shows very large deviations between data from authors for liquid titanium and zirconium, as well as a lack of measurements for the remaining melts. Hence, it is not justified to propose any kind of correlation for those cases.
