Comparative study on the viscosity modeling of the Ag–Au–Cu liquid alloys
Source abstract
Abstract
Abstract With the new CALPHAD-type model proposed in our previous work, the viscosity of the Ag–Au–Cu system was re-optimized. Comparisons were made in the calculated viscosities of the Ag–Au and Ag–Cu liquid alloys at 1373 K among different models. It was found that the CALPHAD-type models perform better than the empirical models. The calculated viscosities of the Ag–Au–Cu liquid alloys with and without ternary interaction parameters were both compared with the calculation results of the previous CALPHAD-type model. Considering ternary interaction, the best fitness with the experimental data could be obtained by our model. The good performance in reproducing the measured viscosities of binary and ternary systems evidences the validity of the new model.
