Influence of low-temperature annealing on the microstructure of cryogenically deformed copper

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$^\circ$C. It was found out that grains with the crystallographic orientation close to $\{112\}$ $\langle$111$\rangle$, $\{4;4;11\}$ $\langle$11;11;8$\rangle$, $\{110\}$ $\langle$122$\rangle$, and $\{130\}$ $\langle$132$\rangle$ had an advantage in the growth, which, apparently, was associated with a relatively low energy stored during the deformation.
