Copper single crystals with the [145] and the [112] axes were deformed in tension at room temperature and dislocation structures were observed by transmission electron microscopy. In the later stage of deformation, layered cell (carpet) structures were formed nearly parallel to the active slip planes. Close examination showed, however, that cell boundaries inclined from the slip plane by several degrees around a ⟨112⟩ axis on the slip plane. The cell boundary densities were approximately proportional to tensile stress and the proportional constants in both crystals were nearly the same. The observed results were consistent with the fundamental assumptions in Takeuchi’s theory of work hardening.
