The diffusion of tracers of silver and cadmium has been measured in AgCd alloys over the range 31 to 37 at% Cd, thus extending the data of Schoen to compositions near to the phase boundary, and facilitating a comparison with Zener relaxation studies by Turner, Dozier, and Williams (see preceding paper). The present diffusion results fit smoothly onto an extrapolation of Schoen's data, but the decrease in activation energies with increasing cadmium content appears to flatten out at the higher concentrations. It is suggested that a temperature dependence of the short range order may contribute to the activation energies.
