| Abstract Scope |
High formability of high-strength automotive sheet aluminum alloys is crucial for preventing surface cracks and roughness during large deformations, such as bending. In this work, 3D x-ray microtomography, along with correlative microscopy, was employed to study the influence of forming on the microstructural evolution of two 6xxx series automotive sheet alloys. The microstructure was characterized by x-ray microcomputed tomography (XCT) to capture the degree of cracking and voiding in intermetallic particles. This was correlated to the particle composition, grain morphology, and substructures captured at various length scales. The mechanisms for microstructural evolution during processing will be discussed. |
