Abstract
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
(

~
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 A

] 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.
