摘　　要：用蚀坑法研究了不同热处理工艺以及Ce含量对铝箔立方织构的影响,结果表明:Ce含量较高时,中间退火300℃ 2 h和成品退火150℃ 3 h+540℃1 h条件下,立方织构含量最高,分布均匀;Ce含量较低时,在390℃ 2 h中间退火和150℃ 3 h+540℃ 1 h成品退火条件下,立方织构含量较高;在一次冷轧前进行400℃ 2 h退火样品的立方织构含量高于未退火的样品。对比发现,Ce含量高的样品,其立方织构的含量也高。The effects of various annealing and the content of Ce on cube texture of high-purity aluminium foils are investigated by means of pit etching in this article. The results showed that in condition of 300℃ 2 h and 150℃ 3 h + 540℃ 1 h, and higher content of Ce, the cube texture increased and the distribution is better.The cube texture decreased as the Ce content depressed. While reduce content of Ce,in condition of 390℃ 2 h and 150℃ 3 h + 540℃ 1 h,the cube texture distribution is better. By contrast,in condition of 400℃ 2 h,the cube texture developed better than that of without heat-treatment before cold-rolled.
