Thermodynamic properties of liquid Zn-Cd alloys investigated by the molecular interaction volume model

Abstract

ABSTRACT The thermodynamic properties, microscopic functions, and diffusivity of liquid Zn-Cd alloys have been predicted by the molecular interaction volume model (MIVM). These properties were also predicted by the self-association model (SAM) (O. E. Awe et al., Appl Phys A. 2017;123:363). Considered the deviation between the predicted values and the experimental values, the MIVM is more reliable and convenient than the SAM. Different from the results of SAM, the asymmetry of properties against concentration calculated by MIVM shows a relatively large reduction, which agreed with the experimental results. Moreover, some cross-over phenomena, which occurred in the conclusions analysed by SAM, were not found in the results from MIVM. The results of this study serve as a supplement to the thermodynamic description of the Zn-Cd system.
