Abstract
Copper single crystals of {1 1 0}〈0 0 1〉 orientation were cold rolled and annealed at 300 °C to study both the deformed state and early stages of static recovery. A homogeneous cellular substructure was generated during rolling with normal direction/rolling direction (ND–RD) sections revealing intersecting bands aligned at an acute angle to RD. These bands exhibit cyclic orientation changes about ND with amplitudes and wavelengths up to 10° and 10 μm, respectively. During annealing, cells situated at the extreme of these orientation perturbations undergo the most rapid coarsening; such a process is similar to the abnormal subgrain growth previously observed in {1 1 0}〈0 0 1〉 oriented aluminium single crystals.
