The annealing of submicrocrystalline copper produced by the equal channel angular pressing followed by rolling was studied using positron annihilation and XRD analysis. In as-prepared samples, positrons are trapped at vacancies, concentration of which is very high (~1.6•10{-4}) and dislocation type defects; however, a few percent of positrons annihilate from a free state. Increasing annealing temperature leads to the formation of vacancy complexes. The main positron trap centers in the temperature range [delta]Т=20-300°С are vacancies and their small complexes of two or three vacancies. The dominant centers of positron trapping in the temperature range [delta]Т=300-670°С are dislocation-type defects.
