Application of the molecular interaction volume model to the assessment of thermodynamic properties of liquid Zn-Bi alloys

摘要

This paper is an attempt to extract useful thermodynamic information from the experimental activity of zinc in Zn-Bi binary liquid alloy at different temperatures. The molecular interaction volume model (MIVM) was adopted to calculate a number of temperature dependent thermodynamic functions, including activity, free energy of mixing, concentration fluctuations in the long-wavelength limits, and diffusion. The reasonable agreement of the modeled thermodynamic parameters with the existing experimental data verified that the MIVM is quite convenient and reliable in the assessment of the thermodynamic properties of binary liquid alloys.
