通过 X 射线衍射研究了直轧和斜轧 AA 3105 铝合金的变形和再结晶织构，以确定定向生长在 P 再结晶织构形成中的作用。再结晶退火后的直轧板中形成了非常强的P织构。相比之下，即使交叉轧制（即沿原始横向方向轧制）织构比直轧织构包含更多接近 P 取向的取向，但交叉轧制板材在退火时并未形成 P 织构。铝合金中P织构的形成需要C成分的存在，因为P取向相对于C取向具有31.1°<122>取向关系。交叉轧制板材中的再结晶织构与定向生长理论非常吻合。
The deformation and recrystallization textures in straight-rolled and cross-rolled AA 3105 aluminum alloy were investigated by x-ray diffraction to determine the role of oriented growth in the formation of the P recrystallization texture. A very strong P texture was developed in the straight-rolled sheet after recrystallization annealing. In contrast, the cross-rolled sheet did not develop the P texture on annealing even though the cross-rolling (i.e., rolling along the original transverse direction) texture contained more orientations close to the P orientation than the straight-rolling texture. The formation of the P texture in aluminum alloys requires the presence of the C component, since the P orientation has a 31.1°<122> orientation relationship with respect to the C orientation. The recrystallization texture in the cross-rolled sheets was in excellent agreement with the oriented growth theory.
