Comparison with a hard-sphere mixture shows that the relation between the different self diffusion coefficients strongly depends on chemical short-range ordering. For the Zr-Ni example, the theory predicts both diffusivities to be practically identical. The kinetics of concentration fluctuations is dramatically slower than that of self-diffusion, but the overall interdiffusion coefficient is equally large or larger due to a purely thermodynamic prefactor. This result is a general feature for non-demixing dense melts, irrespective of chemical short-range order.</dcterms:abstract> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/17115"/> <dc:language>eng</dc:language> <dc:creator>Voigtmann, Thomas</dc:creator> <dc:creator>Meyer, Andreas</dc:creator> <dcterms:title>Atomic diffusion mechanisms in a binary metallic melt</dcterms:title> <dc:contributor>Voigtmann, Thomas</dc:contributor> </rdf:Description> </rdf:RDF>
