Abstract: The development of the recrystallization texture of the alloy AA3104 was investigated by analysis of orientation distribution functions determined by X-ray diffraction, supported by EBSD local texture analysis. A typical β-fiber with nearly 20% Bs orientation {011}<211> was detected in the final hot rolled sheet. At the beginning of annealing at 350°C, the cube component {001}<100> got a sharp increase. TEM results show that the growth of both number and size of precipitation appears to inhibit the advantage of Cube orientation {001}<100> notably after annealing at 350°C for 15min. Finally, it comes out to be a random distributed orientation by full recrystallization.
