Hot-rolled Textures in 5083 Aluminum Alloy

The hot-rolled textures in a 5083 aluminum alloy were measured by electron backscattered diffraction (EBSD) technique. The results show that rolling texture components are uneven at different locations, and the grain boundary planes are textured. Grain boundary planes tend to the {111} orientation at the center of the specimen, and their amount is 50% higher than that of the random distribution case; grain boundary planes on the surface of the specimen tend to the {110} and {112} orientations, and their amount is 28% higher than that of the random distribution case. Moreover, anisotropic distribution of grain boundary planes appears at both low and high angle boundaries.
