采用纯度99.99%的高纯铜进行30%、50%、70%、90%形变量冷轧加工,对不同形变量下高纯铜的晶粒尺寸、分布等微观组织及织构进行了定量研究.结果发现,随着形变量的增加,平均晶粒尺寸、晶粒尺寸方差不断减小,晶粒高宽比(形状因子)逐渐增加,晶粒逐渐转变为纤维状;冷轧织构(Brass、S、Copper)含量逐渐增加,其中Brass织构最多,S织构次之,Copper织构最少.形变量至90%后,冷轧织构含量增至85%以上,晶粒逐渐向标准极射三角形中间部位聚集,在{101}方向有显著聚集,{111}方向始终无明显聚集.α取向线及β取向线上织构含量逐渐增加,均出现明显的集中织构,形变量从70%增加至90%时织构的增加最明显.
