Evolution of microstructure and crystalline texture in aluminum sheet metal subjected to high strain rate biaxial deformation

Electrohydraulic forming was used to biaxially stretch commercial Aluminum 5052 sheet metal workpieces at a high strain rate. Annealed and unannealed workpieces were formed. Specimens were taken from unformed metal and from the formed workpieces. Microstructures were examined with optical microscopy and pole figures were generated from X-ray diffraction data. Microstructures and crystalline textures were compared between formed and unformed and annealed and unannealed metal specimens, and strains were measured from the formed workpieces.
