- Abstract
Commercial alloy AA8011 has been studied by differential scanning calorimetry (DSC) and transmission electron microscopy (TEM) under the condition microstructural homogenized and rolled to different degrees of reduction in thickness, in order to highlight and characterize the interaction between the precipitation and recrystallization, which must occur simultaneously in these alloys subjected to deformation. Calorimetry measurements show differences between the heat flow of samples homogenized and rolled samples. Being reported two extra peaks on severely deformed samples located in the vicinity of the exothermic reactions that characterize the precipitation of the a-FeSiAl and ß-Al3Fe phases. The TEM micrographs show an increase of the dislocation density and a parallel reorganization of the same to the extent that the degree of deformation increases. Recrystallization energy is evaluated, obtaining a value of 106 kJ/ mol.
