Résumé
On a observé des pics de frottement intérieur et de défaut
de module pendant la phase de recristallisation par croissance des grains des
métaux. Les résultats d'analyses avec les rayons X et les observations
métallographiques sont conformes à l'attribution de ces pics à l'émission des
dislocations des joints des grains.
Abstract
Internal friction and modulus defect peaks have been
observed during the recrystallization phase of grain growth of metals. X-ray
diffraction analyses and metallographic observations are consistent with the
attribution of these peaks to dislocation emission from non equilibrium grain
boundaries.
