Electrical resistivity of liquid Al-Mg binary alloys

摘要

The knowledge of the physical properties of liquid Al-Mg binary alloys is of high scientific and practical importance. The Ziman formalism is used to study the concentration dependent electrical resistivity of liquid Al-Mg alloys through an electron-ion potential. Partial structure factor is calculated by using Ashcroft-Langreth equation. The results are compared with experimental findings and the effect of screening function on electrical resistivity is discussed. This reveals that the resistivity data of liquid Al-Mg system are in qualitative agreement with the nearly-free electron picture.
