利用Ｘ射线定量织构分析术和背散射电子衍射花样术，研究了冷轧 ＬＹ１２铝合金的再结晶 织构及重位（ＣＳＬ）晶界的分布，结果表明，高温退火样品的再结晶织构与冷轧样品的织构相似；预回复 低温退火具有增强再结晶立方｛００１｝＜１００＞织构和降低退火Ｓ｛１２３｝＜６３４＞、Ｃ｛１１２｝＜１１１＞及 Ｂ｛１１０｝｝＜１１２＞织构组分的作用；高强度的再结晶立方织构和一定强度的Ｓ织构共存的样品，∑７重 位晶界具有较高的出现频度。
X-ray quantitative texture analysis and backscattered electron diffraction patterning were used to study the recrystallization texture and the distribution of heavy-grain (CSL) grain boundaries in the cold-rolled LY12 aluminum alloy. The results show that the recrystallization texture Which is similar to that of cold-rolled samples. The pre-annealed low-temperature annealing has the advantages of enhanced recrystallization cubic {001} <100> texture and reduced annealing S {123} <634>, C {112} <111> and B {110} The effect of <112> texture components; high-intensity recrystallized cubic texture and a certain strength of S texture coexist samples, Σ7 heavy grain boundaries have a higher frequency of occurrence.
