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.
