摘 要: 采用电场和常规退火以及织构分析(ODF分析)技术，对高纯铝箔再结晶织构的形成及演变规律进行了研究，结果表明电场作为一种重要的势能场对金属的微观结构具有一定的影响。电场退火可以显著地降低高纯铝箔的再结晶温度，平均降低了50～70.℃，扩大了形成强立方织构的再结晶温度范围，提高了再结晶立方织构的强度，但未改变其再结晶织构的形成机制及演变规律。

Abstract: By means of ODF analysis，the formation and development of the recrystallization textures of a high-purity aluminum foil annealed with an electric field were investigated. Results showed that the electrical field，an important potential field， has some effects on microstructures of the metal. Annealed with an electric field, the recrystallization temperature of the foil can be lowered drastically by the average of 50 to 70.℃ and the temperature range at which high cube texture formed is enlarged. The cube texture peak versus annealing temperature is broadened and its strength enhanced. But its formation mechanism remained the same.
Key words: high-purity aluminum foil; texture; annealing with an electric field
