Abstract
The development of the de formation substructure of zone-refined iron is similar to that observed for l ess pure vacuum-melted iron. Qualitative differences with increased purity are noted and are associated with a decrease in the dislocation sources and the necessity for cross-slip . Evidence is presented to show that, in the purest iron investigated, dislocation movement in the foil prepared for transmission electron microscopy is quite unrestricted and that the observed structures may not be typical of the dislocation density and distribution in the bulk.
