Abstract
Crystalline defects other rhtan the essential dislocations are produced by dislocation intersections resulting in debris, which can transform into loops, point defects, and/or nanovoids. The stress concentrations ahead of slip clusters promote void formation leading to incipient cracks. To evaluate the progression of these processes durig the deformation, dunamic disloaction-defect analysis was applied to nominally pure aluminum, Al-Mg and Al-Cu alloys.
