摘 要: 采用電場和常規(guī)退火以及織構(gòu)分析(ODF分析)技術(shù)，對高純鋁箔再結(jié)晶織構(gòu)的形成及演變規(guī)律進行了研究，結(jié)果表明電場作為一種重要的勢能場對金屬的微觀結(jié)構(gòu)具有一定的影響。電場退火可以顯著地降低高純鋁箔的再結(jié)晶溫度，平均降低了50～70.℃，擴大了形成強立方織構(gòu)的再結(jié)晶溫度范圍，提高了再結(jié)晶立方織構(gòu)的強度，但未改變其再結(jié)晶織構(gòu)的形成機制及演變規(guī)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
