摘　　要：采用取向分布函数法分析并研究了冷轧前预处理和冷轧变形量对6082铝合金再结晶的影响。结果表明,6082铝合金的再结晶织构主要由立方织构和旋转立方织构组成。不经过热处理和经过固溶时效处理的试样,随着冷轧变形量的增加,再结晶织构组分明显增加;只经过固溶处理的试样,随着冷轧变形量的增加,再结晶织构组分变化不明显,说明冷轧前固溶处理可以明显弱化再结晶织构。Effects of pre-heat treatments and cold rolling reduction on recrystallization texture of 6082 aluminum alloy were investigated by ODF （orientation distribution function）. The results show that the recrystallization textures of 60g2 aluminum alloy consist of cube texture and rotated cube texture components. For the samples without pre-heat treatment and overaging treatment, the recrystallization textures obviously increase with the increasing cold rolling reduction. However, the recrystallization textures change little with the increasing of cold roiling reduction for the solution-treated samples. The process of solution treatment before cold rolling can weaken the recrystallization texture of 6082 aluminum alloy.
