Abstract
The recrystallization behaviour (recrystallization kinetics, recrystallized grain size and cube texture development) of three commercially significant aluminum alloys (AA5182, AA5052 and AA5005) was modelled using a recrystallization model developed by Vatne et al. The Vatne recrystallization model was originally developed based on thorough experimental investigations of an AA1050 alloy and an AA3104 alloy and has been applied to model the behaviour of AA5xxx alloys in order to assess its applicability to other non-heat treatable aluminum alloy systems. In general, good agreement between model predictions and experimental data was obtained for the AA5xxx alloys studied. The Vatne microstructure model appears to capture some of the important physical mechanisms of recrystallization in hot deformed aluminum as it can reasonably predict the recrystallization kinetics, recrystallized grain size and cube volume fraction as a function of different hot deformation conditions for a variety of aluminum alloys. However, the Vatne model still contains some "tuning" constants that are alloy specific and the model predictions need to be further validated against experimental data especially for multistand scenarios.
