摘　　要：本文以双零铝箔铸轧带坯为试验对象,利用扫描电镜、光学显微镜观察双零铝箔在不同均退工艺下析出相演变情况。结果表明:双零铝箔铸轧板经一道次冷加工率为45.7%时,最佳均匀化退火金属温度应该在530~560℃之间,退火时间应以4~6h为宜。The paper takes the double zero aluminum foil casting and rolling strip as the experimental object,and uses scanning electron microscopy and optical microscopy to observe the evolution of precipitation phases of double zero aluminum foil under different uniform annealing processes.The results show that when the cold processing rate of the double zero aluminum foil casting and rolling strip after one pass is 45.7%,the optimal homogenization annealing metal temperature should be between 530~560℃,and the annealing time should be between 4~6 hours.
