Abstract

Diffusion coefficients and mobilities were determined as functions of concentration in the a phase of the Cu-Zn system. Use was made of incremental diffusion couples to determine the Kirkendall effect at various concentrations. Darken’s analysis was used to calculate the individual diffusion coefficients and mobilities from these data. The general diffusion coefficient is a single-valued function of the concentration in this system to within the limits of accuracy of the experimental methods used. The form of the various functions (diffusion coefficients and mobilities) of concentration is the same in every case: it is essentially the same as the usual D vs c curve.
