It has been found that enhancement of the self-diffusion coefficient of Cu by addition of Sn, In and Sb is expressed by a quadratic equation of the solute concentration rather than a linear one. Combining the enhancement factor of solvent diffusivity determined by the present work with the ...
Self-diffusion of108Pd,65Cu and62Ni in molten Pd40Cu30Ni10P20and of108Pd and62Ni in molten Pd40Ni40P20has been measured by means of capillary techniques between 873 and 1073 K with and without influence of gravity. The diffusion coefficients are similar for all elements in the r...

Two-phase mixtures, from metallic alloys to islands on surfaces, undergo coarsening wherein the total interfacial area of the system decreases with time. Theory predicts that during coarsening the average size-scale of a two-phase mixture increases with
