Investigation of atomic transport and surface properties of liquid transition metals using scaling laws

To test the validity of existing scaling laws which express the possible relationship between the excess entropy and transport properties, the diffusion and viscosity coefficients of liquid Fe, Co and Ni metals are calculated. To predict excess entropy, the pair distribution functions are calculated from the solution of Ornstein-Zernike integral equation. It is shown that the scaling laws proposed by Dzugutov for diffusion and by Li et al. for viscosity lead to a good estimation for diffusion and viscosity coefficients at the melting point.
