Microstructure inhomogeneities between the core and the surface regions of cold rolled pure aluminum thin foils were documented and characterized by transmission electron microscopy. Different dislocation types were identified and these were recognized as responsible for the observed microstructure inhomogeneities. It resulted that as the foil thickness reduces to 10 mu m the core region tends to form single grains decorated by few tangled dislocations, while the surface regions are characterized by cell and grain boundaries.

Abstract
Microstructure inhomogeneities between the core and the surface regions of cold rolled pure aluminum thin foils were documented and characterized by transmission electron microscopy. Different dislocation types were identified and these were recognized as responsible for the observed microstructure inhomogeneities. It resulted that as the foil thickness reduces to 10 mu m the core region tends to form single grains decorated by few tangled dislocations, while the surface regions are characterized by cell and grain boundaries.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
