摘　　要：利用光学显微镜(OM)、电解抛光和阳极覆膜研究了在退火前不同的冷轧变形量对1235超薄双零铝箔坯料显微组织的影响。结果表明:在相同的退火条件下,退火前较大的冷轧变形量可以获得较小尺寸的化合物,而且再结晶晶粒均匀细小。这有利于提高铝箔坯料质量,降低铝箔针孔率等缺陷。The effects of cold rolling deformation before annealing on microstructure of the blank of 1235 ultra-thin double zero aluminum foil were investigated by using optical microsco （OM）, electrolytic polishing and anode film coating. The results show that under the same annealing conditions, larger cold rolling deformation before annealing can obtain compounds with smaller sizes, and recrystallization grains are uniform and fine. This is beneficial to improve the quality of aluminum foil blank and reduce the aluminum foil pinhole rate and other defects.
