Copper single-crystals were wire drawn far into stage III and into the onset of stage IV. TEM investigations revealed the well known dislocation cell structure. High resolution X-ray …
This work is part of a continuing effort to develop a unified picture of the role of geometrically necessary dislocations (GNDs) in the evolution of the dislocation distribution of …

Previous studies on the strain rate sensitivity of the stress for copper single crystals and polycrystals generally agree in defining a limiting value~= 103 s 1 between the static and the …

Tapered copper single crystals oriented for single slip are deformed plastically at room temperature and at 77 K. TEM investigations at resolved shear stress levels of 20, 30, and …
Long-range internal stresses in dislocation cell and subgrain structures were investigated experimentally. The transition of the dislocation structure from cells to subgrains was …

The development of dislocation structure along the stress strain curve in stage I and the beginning of stage II of Cu single-crystals was followed up by means of etch pits. The …
