Samples from the center of plates of rolled aluminum alloys AA 8090 and 7055 were investigated using microbeam diffraction and polychromatic synchrotron x-ray radiation. Transmission Laue patterns from different parts of the samples were compared and analyzed for the presence of mesotexture similar to that observed previously in the center of plates of aluminum alloy AA 2090 (i.e., near single-crystal volumes of 5 to 10 or more adjacent grains with nearly identical orientation). The macrotexture and grain morphology of the AA 8090 samples were quite similar to those of samples of AA 2090; the macrotexture and grain morphology of the AA 7055 sample differed from those of AA 2090. Approximately 10% of the AA 8090 volume consisted of material with the near single-crystal mesotexture (compared to about 40% typical for AA 2090) while no near single-crystal volumes were observed in the AA 7055 material.
