Abstract: The effects of rolling driving methods and technical factors on the microstructures and mechanical properties 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 aluminum 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 location recrystallization is more likely to come into being. The effects of the dynamic recovery phenomena and the dynamic primary location recrystallization on the comprehensive final product ratio and the quality of aluminum foils were discussed.
