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 T m and boiling point T b is modeled in terms of the relationship among D , liquid viscosity η , and liquid–vapor surface tension γ lv . 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.
