It is becoming increasingly important to control these microstructural changes in order to optimise the subsequent processing route and thereby produce a cost-effective product. The ability to model the microstructural evolution of the alloy during rolling would greatly reduce the development cost and development time of a particular rolling schedule. This thesis investigates the recrystallization behaviour of A1Mg for a three pass rolling process. Equations describing the recrystallization process are implemented into a Finite Element code, and the effect of changing the roll speed is investigated. The results indicate that further work is required to empirically characterise the recrystallization behaviour of the particular alloy in question.
