〈110〉‐orientated single crystals of high purity copper were deformed in tension up to 80% elongation. Sections of the deformed material were examined by HVEM before and after annealing in situ. Additional measurements by a texture goniometer confirmed and supplemented the metallographic results. The orientations of all recrystallized micrograins can be interpretated as the result of multiple annealing twinning. Since the grain boundary energy may be lowered by twinning the new orientations may be selected for this reason. These results can explain the recrystallization textures observed by X‐ray techniques.
