| Abstract Scope |
To pursue green and low-carbon production, designing and developing continuous casting to replace direct chill casting for producing 8021 aluminum foil sheets for aluminum-plastic film holds significant application potential. This work investigated the evolution of the precipitates, microstructure, and texture of 8021 sheets during the cold rolling process, along with the influence of the annealing process on them. The results indicate that the primary precipitates are Al₃Fe, along with a small amount of α-AlFeSi. As the annealing temperature increases, the average size of the precipitates initially decreases slowly, reaching its minimum at 400°C, and then significantly increases to 1.20 μm with a further temperature rise. The recrystallized grain size increases gradually from 28 to 38 μm. The initial texture of the sheets is mainly {112}<111>, which being weakened after homogenization annealing and significantly strengthened after cold rolling deformation. During annealing under 300-500°C, the {001}<100> texture dominates. |
