Temperature dependence of self-diffusion in liquid metals

Application of the Hard Sphere Theory to the Diffusion of Binary Liquid Alloy Systems

“…The application of (4) (9) With the aid of (9), (7) and (5) it is possible to calculate the temperature dependent self-DC. Good agreement with experimental results was obtained using the correction factor [5,7] C( V ) = 0.73 rjmlrj.…”

“…The application of the HS theory [5,7] to binary liquid alloys, which are considered as mixtures of two HS liquids, requires some additional assumptions…”

Development of an atomic mobility database for liquid phase in multicomponent Al alloys: focusing on binary systems

“…[33] determined the self-diffusion coefficients in liquid Zn overthe temperature range of 693 -873 K. Vadovic and Colver [34] calculated the self-diffusion of liquid Zn through Stokes-Einstein equation using the Goldschmidtdiameteroverthe temperature range of 600 -800 K. Recently Iida et al [35] also investigated the self-diffusivity of liquid Zn by means of a modified Stokes-Einsteinf ormula. All the reported selfdiffusion coefficients in liquid Zn agree well with each other, and they are thus employed to determine the atomic mobility for liquid Zn.…”

Infinite dilution diffusion coefficients in liquids

“…A major drawback in the use of Equation (16) is that the molecular lengths are not generally known. Numerous authors, including Ashcroft and Lekner (1966) and Vadovic and Colver (1970), have related the molecular length parameter to the volume at the melting point, or a{{ = y v,p (17) where y is a constant for a given class of compounds. Dullien has suggested that the critical volume be used to obtain the length parameter, that is…”

“…It has further been shown by Vadovic and Colver (1972) that for most organic compounds, the following relationship holds Thus the choice of V, or Vc depends entirely on the availability of critical or melting point data. Alternately, Vadovic and Colver (1972), from a consideration of the rigid sphere theory of Longuet-Higgins and Pople (1956), have presented the following equation: Both these equations have been shown to accurately predict self-diffusion in liquids.…”
