Recovery studies of cold rolled aluminum sheet using X-ray line broadening and activation volume determinations

The microstructure of cold rolled metals is highly complex, but characterization of its transformation to the recrystallized state is essential to design thermal–mechanical processing of sheet products. In this study recovery leading to continuous recrystallization was examined by both X-ray line broadening and measurement of activation volumes at 78K as a function of isochronal anneals to characterize the recovered structure wherein …
