Influence of precipitation on recrystallization texture of AA3104 aluminum alloy

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 {011}<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 {011}<100> notably after annealing at 350 °C for 15 min. Finally, it comes out to be a random distributed orientation by full recrystallization.
