Abstract

Self-diffusion of 108Pd, 65Cu and 62Ni in molten Pd40Cu30Ni10P20 and of 108Pd and 62Ni in molten Pd40Ni40P20 has 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 respective alloys and show the temperature dependence of diffusion of the mode-coupling theory. The results are discussed with respect to structural models of Pd-based bulk amorphous alloys.
