摘 要: 考察了不同冷軋工藝生產(chǎn)的1050H19電站用空調(diào)箔的性能， 并結(jié)合X射線織構(gòu)分析和透射電鏡微觀結(jié)構(gòu)分析結(jié)果， 討論了織構(gòu)及微觀結(jié)構(gòu)對深沖性能的影響。 結(jié)果表明： 4種工藝中試樣的變形織構(gòu)均屬于典型的Cu型織構(gòu), 不存在再結(jié)晶的R織構(gòu)和立方織構(gòu)組分， 主要織構(gòu)組分仍為Cu織構(gòu)， 但取向密度不同， 易開裂者Cu織構(gòu)的取向密度值達(dá)160， 織構(gòu)較強(qiáng)， 并含有較難變形的織構(gòu)組分P織構(gòu)和戈斯織構(gòu)。 經(jīng)分析可知，由于減少道次壓下率和實施中間停留， 使得鋁箔消除了較難變形的織構(gòu)組分， 減小了Cu取向織構(gòu)的取向密度， 宏觀上表現(xiàn)為深沖開裂傾向的減小，從而改善了鋁箔的深沖性能。

Abstract: The property of 1050H19 aluminum foils used in the air-conditioner of electric station by cold rolling-process was studied. Combining with X-ray goniometer and TEM microstructure analysis, the effects of textures and microstructures on deep-drawing properties were discussed. The results show that deforming textures in the specimens using four cold rolling-processes were all typical Cu components, and recrystallized R-texture and Cube-texture do not exist. Cu-texture is still the predominant component but has different orientation densities. The orientation densities of Cu-texture in the specimens being prone to crack can reach 160 and the textures are high, and the samples contain difficult deforming P-texture and Gross-texture. The analysis indicates that with decreasing rate of reduction/rolling-press and the execution of intermediate holding, difficult deforming textures are eliminated, and orientation density of Cu-texture is weakened. Thus, deep-drawing cracking tendency of aluminium foils decreases macroscopically and deep-drawing properties are improved.
