Diffusion of Cobalt in Beta-Uranium

Abstract
The solute diffusion of cobalt in beta-uranium was measured using the thin-layer sectioning technique. The results can be expressed by D= 1.54×10−2 exp(−27 450/RT) cm2/sec. The diffusivities of cobalt are higher by about three orders of magnitude than the self-diffusion coefficients in beta-uranium. The possibility of cobalt diffusing by means of the combined substitutional-interstitial mechanism has been examined.
