摘 要: 采用取向分布函数法研究了冷轧6111铝合金板的再结晶织构。 结果表明：冷轧6111铝合金薄板的再结晶织构主要由两种织构组分构成， 一种是绕板法向旋转约15°的立方织构组分Cube＋ND15，另一种是{110}〈111〉织构组分； 该两种再结晶织构组分与主要形变织构组分均具有〈111〉型取向关系， 其中Cube＋ND15组分与形变织构中的S组分间具有近似的40°〈111〉取向关系， {110}〈111〉组分与形变织构中的Copper组分间具有33°〈111〉取向关系； 在退火保温过程中， 再结晶织构的取向密度首先达到最大值，然后略有降低， 经一定时间后基本不再变化。

Abstract: The recrystallization textures of Al alloy 6111 were investigated by means of orientation distribution function (ODF). The results show that the recrystallization textures in cool rolled Al alloy 6111 are composed of the cube orientation rotated about 15° around normal direction (i.e. Cube+ND15)and the orientation {110}〈111〉. The recrystallization texture components can be derived by a rotation of the main rolling texture components. There is an approximate 40°〈111〉 orientation relationship between Cube+ND15 and S orientation, and a 33°〈111〉 orientation relationship between orientation {110}〈111〉 and Copper orientation. During holding temperature of solution treatment, the orientation densities of the recrystallization texture components firstly increase and maximize and then reduce slightly, but keep constant when holding time is beyond 10 min.
