Li et al [3] have measured the texture developed in one pass in aluminum and demonstrated that these ECAP texture orientations can be derived from those for negative simple shear, by increasing the f1 of simple shear ideal orientations by 45o, which is the angle that transforms the shear reference system X’Y’Z’ to the billet axes system XYZ in a 90o channel ECAP die, while the other two Euler angles remain the same (please refer to Fig.1 where an ECAP processed billet is displayed and the two sets of axes are shown).
Ferrase et al [6] have combined ECAP with rolling and stated that with ECAP using route A and BC there is a global decrease of texture strength and attributed this to mechanically induced dynamic recrystallization, which occurs at high level of deformation and promoted grain rotation and grain boundary sliding.
Hirsch et al. [4] demonstrated that the copper to brass transition of the rolling texture that happens at intermediate rolling reductions, is mainly related to lowering the stacking fault energy (SFE) and deformation twinning, which in our case would be very difficult to form due to the high stacking fault energy of aluminum and ease of cross slipping.
