The influence of deformation twinning on the alloy type texture formation in fcc metals was examined by rolling of copper and Cu-6 at%Al alloy single crystals having near (123)[\bar2\bar11] and (111)[0\bar11] orientations.
Copper crystals exhibited deformation only by slip and developed the {123}〈211〉 texture. In the alloy crystals, deformation twinning occurred extensively from low rolling reductions. The twinned crystals rotated not toward {110}〈001〉 but toward {111}〈101〉 and then a double {111}〈101〉 intermediate texture was formed.
The displacement from {123}〈211〉 to {111}〈101〉 and the stabilization of {111}〈101〉 in the alloy crystals were discussed in terms of twinning shear rotation and latent hardening. Formation of the components having a (111) plane parallel to the rolling plane was concluded to be one of the important characteristics of the alloy type rolling texture.
