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 different cold rolling deformation on the microstructure of 1235 ultra-thin double zero aluminum foil billets were investigated by optical microscope (OM), electrolytic polishing and anode coating. The results show that under the same annealing conditions, larger size of cold rolling deformation before annealing can obtain smaller size compounds, and the recrystallized grains are fine and uniform. This is conducive to improving the quality of aluminum foil billet, reducing the porosity of aluminum foil and other defects.
