Abstract Scope |
8021 aluminum foil is an important electrode material for lithium-ion batteries. Continuous casting process for producing 8021 aluminum foil sheets has been a hot research topic. The initial microstructure of the continuous casting sheets with thickness around 7 mm is crucial in determining the quality of the foil products. This study investigated the effects of homogenizing annealing process on the microstructure, precipitates, texture, and mechanical properties of continuous casting 8021 aluminum foil sheets. It was found that the size of the precipitates shows a trend of initially slow reduction followed by significant growth with increasing annealing temperature; grain size gradually increases simultaneously with a significant increase when the temperature exceeds 500°C. The textures on the surface and interior of the sheets exhibit notable differences: the surface displays strong {001}<110> and {112}<110> textures, while the interior shows weak {112}<111> texture. The textures were also influenced by the annealing temperature. |
