摘 要: 采用取向分布函数(ODF)法研究了预先热处理对6111铝合金的冷轧和再结晶织构组态的影响。 结果表明: 预先热处理因改变基体的成分和第二相的析出状态而显著影响6111铝合金的形变织构和再结晶织构; 热轧板不经预处理而直接冷轧, 其再结晶织构主要由绕法向旋转了15°的立方取向(Cube+ND15)和{011}〈111〉取向构成; 冷轧前进行过时效处理, 其再结晶织构主要由绕法向旋转了20°的立方取向(Cube+ND20)和{011}〈122〉取向构成;冷轧前进行固溶处理会显著提高冷轧织构中Brass和Goss组分的取向密度,再结晶织构明显弱化, 而且Cube+ND20组分绕法方向(ND)产生很大的漫散,接近于{001}〈UVW〉纤维织构。

Abstract: The effects of pre-heat treatment on rolling and recrystallization textures were investigated by means of orientation distribute functions (ODFs). The results show that the pre-heat treatments have significant effects on both rolling texture and recrystallization texture. The recrystallization texture of sample hot rolled and then cold rolled consists of cube orientation rotated by 15° round normal direction (ND) and {011}〈111〉orientation. The recrystallization textures consist of cube orientation rotated by 20° round normal direction (ND) and {011}〈122〉orientation for samples overaged and then cold rolled. The orientation intensities of Brass and Goss components of cold rolling texture are raised remarkably for samples solution-treated, and the orientation intensity of the rotated cube orientation of recrystallization texture is obviously lowered. The rotated cube orientation is scattered round normal direction, closing to {001}〈UVW〉 fibre texture.
