Abstract
Self diffusion of 48V in vanadium single crystals was reinvestigated over the temperature range 724–1842°C. Contribution to diffusion from migration along short-circuit paths at the lower temperatures was avoided by applying a micro sectioning technique specially developed for this study. The change in slope of the Arrhenius curve reported to occur at about 1350°C was not observed in this investigation, but has been observed to occur in the vicinity of 1642°C. The data in the temperature range 724–1642°C can be fitted to the relation
