Thermophysical Assessment of Lead Magnesium Alloy at Different Temperatures

Abstract

Abstract: The mixing behavior of lead–magnesium liquid alloy is studied using different modeling equations at various temperatures. The quasi-lattice model has been employed too analyze the concentration-dependent thermodynamic and structural properties of lead–magnesium liquid alloy. To validate the model, the obtained theoretical results are compared with experimental results. The viscosity of the alloy has been studied by the Kozlov–Romanov–Petrov equation, the Kaptay equation, and the Budai–Benko–Kaptay model, whereas surface tension has been studied by the Butler equation, tatistical mechanical approach, and the Compound formation model. The primary focus of this study is the interaction parameters among the atoms of the alloy. The alloy shows the moderately interacting and ordering nature within the entire concentration of lead. There is reasonable agreement between the theoretical and experimental data at 973K. The study concludes that the alloy depicts ordering tendency and viscosity and surface tension both decrease with increase in temperature.
