Abstract

Annealed pure copper strips were taken as raw materials, and after the processes of foil rolling, the rolled copper foils were fabricated. The effect of foil rolling reduction on microstructure, texture and bending property of the rolled copper foils was studied. The results show that the cross-sectional microstructure of the rolled copper foil consists of elongated grains and the adjacent grain boundaries spacing gradually decreases with the increase of the rolling reduction. When the reduction reaches 90.7%, the adjacent grain boundaries spacing is only 0.52 μm. Rolling textures of the rolled copper foils mainly consist of C, S and B orientation components. With the increase of reduction, the whole intensity of rolling texture increased, and the orientation concentrated continuously. The rolled copper foil with reduction of 90.7% has the best bending resistance, whose fatigue life is more than 300 times. The basic reason for the enhancement in bending performance of copper foils may be that a great foil rolling reduction makes their grains much thinner and their texture highly intensified.

Key words: metallic materials rolled copper foil rolling reduction microstructure and texture bending property mechanism
