摘 要: 采用取向分布函數(shù)法研究了冷軋6111鋁合金板的再結(jié)晶織構(gòu)。 結(jié)果表明：冷軋6111鋁合金薄板的再結(jié)晶織構(gòu)主要由兩種織構(gòu)組分構(gòu)成， 一種是繞板法向旋轉(zhuǎn)約15°的立方織構(gòu)組分Cube＋ND15，另一種是{110}〈111〉織構(gòu)組分； 該兩種再結(jié)晶織構(gòu)組分與主要形變織構(gòu)組分均具有〈111〉型取向關(guān)系， 其中Cube＋ND15組分與形變織構(gòu)中的S組分間具有近似的40°〈111〉取向關(guān)系， {110}〈111〉組分與形變織構(gòu)中的Copper組分間具有33°〈111〉取向關(guān)系； 在退火保溫過程中， 再結(jié)晶織構(gòu)的取向密度首先達到最大值，然后略有降低， 經(jīng)一定時間后基本不再變化。

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.
