The rolling texture of electrolytic copper after a reduction of thickness 88.7% can be described as (110) [112], (112) [111] and a texture (3,6,11) [533]. During annealing at lower temperature, the recrystallization texture was found to be (100) [001] + (358) [352] plus a (122) [212] texture which is a twin position with respect to (100) [001] texture. Together with the raising of the annealing temperature, a decrease of (358) [352] texture and on increase of (100) [001] texture was observed. When annealing temperature reached to 900℃, a nearly perfect cubic texture was developed.During annealing at higher temperature (900℃), grains having (100) [001] oriention appeared first. Then, an overall "recrystallization in situ" took place and the (100) [001] grains tended to grow selectively at the expense of the others. Finally, a concentrated (100) [001] texture was produced.The geometric relationship between the rolling texture and the recrystallization texture was investigated. In general, the change from the rolling texture to the recrystallization texture may be suggested as a rotation of 45°, 22°, 38° about a common [111] axis. The ideal pole-figures, constructed according to the above relationship were found to be in good agreement with the experimental results.It was found that the different rate of heating and the different annealing procedures produced no signeficant effect on the final recrystallization texture. The temperature of annealing, however, was the main factor contributing to the development of the recrystallization texture.
