Description:
The microstructure and tensile property of 105mm thick 5083 aluminum alloy hot-rolled plate in different thickness layers were investigated by optical microscopy, scanning electron microscopy, transmission electron microscopy and tensile tests. The results show that along the thickness direction, the microstructure and tensile property are inhomogeneous, and a “double low” phenomenon, which has low strength and plasticity, occurs in the central area. There are many sub-micron sized second phases in the center and near-center area, which cause two completely different dislocation distribution states. they can effectively prevent the dislocation movement during plastic deformation, and improve the strength of the alloy.
