Résumé
On a suivi les premières étages de la recristallisation de lames minces d'aluminium par observations de frottement intérieur, module élastique, métallographie et X.R.D.. Les résultats sont interprété en termes d'émission des dislocations par les joints de grains, associé à la nucléation.
Abstract
The initial recrystallization stages of cold rolled Al sheets have been followed by internal friction , elastic modulus, metallographic and X-ray diffraction observations. The results are interpreted in terms of dislocation emission from the grain boundaries, connected with nucleation.
