The influence of second phase particles on texture during rolling of Al 3104

The determination of the role of second-phase particles on texture evolution is critical since on the one hand their distribution and size can be controlled through homogenization and on the other hand their presence affects the response of the final product. An effective design of the thermomechanical stages could provoke the creation of favorable second phase particles and therefore reinforce the presence of the desired texture components for a certain application. The present study focuses on the effect of second phase particles on the texture evolution of cold-rolled AA3104 DC strips subjected to different reductions and annealing conditions. In particular, the resulting dominant crystallographic components near the areas of influence of second phase particles are examined concerning their size and in the context of the overall crystallographic texture. In addition, the nucleation points that were induced after various cold roll passes and annealing processes were examined and correlated to the PSN effect of the detected second-phase particles. Based on this categorization, their impact on the rotation of the nearby orientations as well as on the overall texture was studied. It was found that texture was mostly affected by particles with a mean diameter between 1 μm and 5 μm (accounting for 20–30% of the total second-phase particles), a behavior that was further confirmed through the annealing processes.
