The microstructure and crystallographic texture of copper electrodeposited onto a graphite substrate were examined by scanning electron microscopy, and electron backscatter diffraction. A high twin fraction of 80% was achieved using a pulsed electrodeposition technique under the current density of 0.5 A/cm 2. A new twinning cluster, termed in this paper as pseudohexagonal composite twins, was observed in pseudohexagonal grains. The pseudohexagonal composite twins possess the crystallographic feature of a rotation angle of 60° around an axis of 111.
