    Abstract

    The high-resolution electron backscatter diffraction (EBSD) technique was applied to study electrodeposited and subsequently annealed nano-scale copper wires. The mean grain size was found to be coarser than the mean free path of electrons (~ 40 nm). The wires were shown to contain a notable fraction of low-angle boundaries as well as annealing twins. The material was found have a strong {111}<110> texture.
