%X electrolytic tough pitch (etp) and fire refined high conductivity (frhc) copper samples were severely deformed at room temperature by equal channel angular pressing (ecap) up to 16 passes (¦Ĺ ~ 1 per pass), following route bc. the effect of the initial texture on the evolution of texture after the ecap process for both materials was analyzed. the annealed materials present a marked anisotropy, with a texture controlled by the <110> fiber. according to the orientation distribution function (odf), this initial behavior allows the presence of a strong c ({001} <110>) component after the first two ecap passes in both coppers. however in the second pass the c component significantly increases in the frhc copper, whereas the etp copper presents a much more balanced behavior of the a1* (111)[ 2]and a2* (111)[11 ]components. the textures obtained for both coppers after each ecap pass exhibit predominant orientations with continuous distributions along the orientation fiber with simple shear texture.
