The deformation and recrystallization textures of 6111 Al alloy with various precipitation states have been investigated by means of the orientation distribution functions (ODFs). It was found that the precipitation state had significant effects on both rolling and recrystallization textures of Al alloy. For the alloy with no or little precipitate, the orientation intensities were distributed more homogeneously along the β-fiber. With increasing aging temperature, the orientation intensities along the β-fiber increased firstly and decreased then. Simultaneity, the orientation intensities along the β-fiber were distributed more and more inhomogeneously. On the other hand, with the precipitates increasing the recrystallization textures changed gradually from {001} and very weak {011}<111> orientation to the strong {001}<311> and {011}<111> orientation.
