Abstract
Cube texture after cold rolling has been studied to clarify effects of annealing time and temperature for Al foils with varying purifies from 99% to 99.99%. The foils of 0.1㎜ thickness were annealed finally at temperatures from 300℃ to 600℃ for 1, 3, 5 and 7 hours in 10^(-3)torr vacuum. It was found that the highest cube texture was obtained by repeating hot and cold rolling, and final annealing at 600℃ for 3 hours, while the formation of cube texture was reduced as the annealing time augmented from 3 to 7 at 600℃, because of the coarse recrystallization grain growth during annealing process. It could be known that forming time and leakage current more increased in low purity Al foil than high purity.
