Recrystallization of an AlMgSi alloy after different modes of hot deformation
MetadataShow full item record
Recrystallization of an AlMgSi alloy has been studied after deformation in torsion and plane strain compression. The main emphasis has been focused on describing the development of nuclei in shear deformed material, and a physically based model has been developed to predict the course of recrystallization in torsion. This model is based on and compared to a previously developed model by Vatne et al. describing the recrystallization in plane strain compressed material. To test the model predictions, recrystallization experiments on plane strain compressed and torsionally deformed material have been carried out. This looks at 6060 alloy, no instance of 6061.
