Abstract
Types of dislocation substructures produced on straining nickel single crystals with the [001] compression axis are identified in the temperature range from 77 to 673 K. The change in the volume fractions of the substructural types is shown to be correlated with the deformation stages in the work-hardening curves in the strain temperature range studied. Qualitative and quantitative descriptions of the evolution of the dislocation substructures are given. Pathways by which a cellular substructure can be transformed into a microbanded or fragmented substructure and a plausible fragmentation mechanism for the microbanded substructure are discussed.
