Effects of rolling technical factors on microstructures and mechanical properties of aluminum foils

The effects of rolling driving methods and technical factors on the microstructures and texture analysis.The erties of aluminum foils based on the industrial trials were studied by TEM,tensile test and texture analysis.The results show that there exist obvious dynamic recovery and primary location re-crystallization phenomena in the alu-minum foils during high-speed rolling.Meanwhile the phenomena become more obvious as the rolling speed or the reduction increases,especially in the asymmetrical rolling process with single-roller driving,the dynamic primary lo-cation recrystallization is more likely to come into being.The effects of the dynamic recovery phenomena and the dy-namic primary location recrystallization on the comprehensive final product ratio and the quality of aluminum foils were discussed.
