dc.description.abstract An investigation of the characteristics of yielding and flow in polycrystalline and single crystal vanadium has been carried out. The effect of grain size, temperature and strain rate on these properties was studied. It was found that there is no similarity between the mechanisms of yielding and flow, in vanadium which is in disagreement with work on iron. The results of tensile tests suggest that the mechanism controlling thermally activated flow is probably either the Peierls-Nabarro force or the non-conservative motion of vacancy jogs. Some inadequacies of these mechanisms suggest that there may not be a single mechanism controlling thermally activated flow. Yield points were observed in the stress-strain curve upon reloading a tensile specimen under certain conditions and these are explained in terms of Snoek ordering. en
