| Abstract: | The microstructure formation during annealing of cryogenically deformed copper was studied. It was shown that the primary recrystallization was completed already after a one-hour annealing at 150°C. It was found out that grains with the crystallographic orientation close to {112}〈111〉, {4; 4; 11}〈11; 11; 8〉, {110}〈122〉, and {130}〈132〉 had an advantage in the growth, which, apparently, was associated with a relatively low energy stored during the deformation. |
