中间退火对高纯铝箔立方织构的影响

The Effect of Middle Annealing on Cube Texture of High purity Aluminum Foils

采用晶体取向分布函数 (ODF)研究和分析了中间退火对高纯铝箔立方织构的影响。研究结果表明 :中间退火对高纯铝箔冷轧形变织构影响不大 ,但对成品退火箔材中立方织构和 R织构含量产生重要影响 ,在 30 0℃ / 2 h中间退火条件下 ,成品箔材中再结晶立方织构取向密度最大 。

The effect of middle annealing on cube texture of high purity aluminum foils was investigated by means of orientation distribution functions (ODFs) The results show that the deformation textures except the Cu component were rarely affected by the middle annealing temperatures But it bring about strong influence on the cube texture of aluminum foils after the final annealing The cube texture is decreased as the middle annealing temperature is increased, while the R component is changed a little The cube texture is the strongest in the middle annealing at 300℃/2h
