Recrystallization of a channel die compressed copper single crystal with (112)[11(1)over-bar] orientation

Several steps of the recrystallization of (112) [11 (1) over bar] copper single crystals initially deformed in imposed flat compression are studied using partially recrystallized domains. It appears that macroscopic shear bands are preferential sites for nucleation. In addition, it may be noted that statistically the nuclei do not have a special crystallographic orientation while, when recrystallization has progressed more, it may be verified that an orientation relationship (30-40 degrees <111>) between the recrystallized grains and the deformed matrix exists, which shows that there is a mechanism of oriented growth.
