Abstract:
??????The hot-rolled textures in a 5083 aluminum alloy were measured by electron backscattered diffraction technique, and the results show that rolling texture components are developed unequally at different locations, moreover, grain boundary planes are also textured. Grain boundary planes favor the {111} orientation at the center of the specimen, and their population is 50% higher than the random distribution case, whereas grain boundary planes favor the {110} and {112} orientations on the surface of the specimen, and their population is 28% higher than the random distribution case. Moreover, this anisotropic distribution of grain boundary planes occurs at both low and high angle boundaries.
