Abstract Scope |
Ductile failure of metals proceeds by nucleation, expansion and coalescence of voids in the microstructure. The evolution of voids is monitored by tomography. At the same time precipitates in the metal are visualized. The initial microstructure of the polycrystalline metal (AA1050) has been characterized by 3DXRD but due to spot overlap this is not possible in the deformed microstructure at the strain level where voids appear. Instead tracking of the precipitates across deformation steps is utilized to follow the morphology of the grain structure. To obtain the local crystallography around voids, scanning-3DXRD is employed. The experimental data will serve as input to crystal plasticity simulations. |
