Temperature dependence of self-diffusion coefficient in several liquid metals

Abstract

The temperature-dependent self-diffusion coefficient D(T) in liquid metals between the melting temperature Tm and boiling point Tb is modeled in terms of the relationship among D, liquid viscosity η, and liquid-vapor surface tension γlv. The model predictions for D(T) correspond to available experimental and molecular dynamics (MD) simulations results for liquid alkali metals Li, Na, Rb and Cs, semi-metal Al, transition and noble metals Ni, Cu, Ag and Au. © 2006 Elsevier B.V.
