Anisotropy and Forming Limit Diagram Comparison of DC and CC 5xxx O Temper Aluminum Alloy Sheets

摘要

The microstructures of the aluminum alloy sheets were studied by using optical and scanning electronic microscopes. Textures of DC and CC 5xxx aluminum alloy sheets at O-temper were measured by X-ray diffraction method and Forming Limit Diagrams (FLD) along different angles with rolling direction were obtained. The relationship between anisotropy (crystallographic texture) and FLDs was discussed. It was found that movement and changes in shape of FLDs of two Al alloys were caused by rotations of Cube, S, Copper and Brass textures.
