Abstract
In this study, single-crystal samples of pure copper with stable orientations – Br (110)[112] and G(110)[001] – were impact-loaded in a channel die, with the punch driven by explosive energy, to achieve a strain rate of 4 × 105 s−1. Microstructural characterization was conducted on samples deformed up to 60%, using optical microscopy and SEM across a wide range of scales. Texture evolution was analysed through X-ray diffraction and SEM/EBSD. Both orientations exhibited highly unstable behaviour due to deformation twinning and the development of plastic flow instabilities in the form of deformation bands. In G(110)[001]-oriented crystals, twinning occurred on two planes, while in Br(1-10)[112]-oriented crystals, twinning occurred on all four {111} planes, which are highly favoured for slip activity during deformation. The formation of plastic flow instabilities in narrow regions resulted from the dominance of a single slip system in selected regions of the Br-oriented crystal, or a pair of highly favoured slip systems in the G orientation.
