In single and polycrystalline copper rolled to a reduction of 95 %, the topographic arrangements of crystallite
orientations were determined over large areas by means of electron microscopy. Correlated data on orientation,
diffraction site, and transmission pictures in three cross-sections perpendicular to the normal, rolling and transverse
directions were obtained and evaluated. These results were complemented by X-ray studies of the texture. The
rolled polycrystalline structure consists of roughly disc-shaped regions of uniform orientation which are fairly
strongly misoriented with respect to each other. The planes of the discs lie paral.lel to the rolling plane. Within these
regions of uniform orientation lie elongated subgrains extended in the longitudinal and transverse directions. In a
surface layer of a few microns thickness the dryly rolled single crystals have essentially a (100)[011] texture. This is
independent of the orientation of the interior of the material. The observed structures are discussed with respect to
possible formation mechanisms.read more

TL;DR: In this article, the authors considered the problem of estimating the orientation correlation function of the grain and phase boundaries using series expansions in terms of symmetrized harmonic functions, which is the most economical representation of these functions.
