Abstract
Crystallographic orientation of abnormal coarse grains formed in copper after severe cryogenic deformation and further long-term storage at room temperature was analyzed. The orientation was found to be close to cube texture {100}<100>. This phenomenon was shown can be associated with annealing twinning.
