Extraction of Diffusion Correlation Information from Tracer, Interdiffusion and Ionic Conductivity Data

Abstract:

In this paper, the current understanding about the relationships between tracer diffusion coefficients, interdiffusion coefficients and d.c. ionic conductivities in metallic alloy and ionic systems is reviewed with emphasis on recent progress. Quasione component systems are analyzed in terms of the Haven Ratio (and tracer and collective correlation factors). Two and three component alloy systems are analyzed in terms of the Darken-Manning equation and vacancy-wind factors (and tracer and collective correlation factors). Ionic systems with two mobile components are analyzed in terms of a corrected Nernst-Planck Equation.
