Abstract
A through process model for high temperature extrusion of AA3xxx aluminum alloys is presented. An overview of the various chemistry dependent sub-models, e.g. homogenization, extrusion, cold deformation and annealing, are described with an emphasis on the linkages between the models. Examples are presented to illustrate the importance of including the linkages between the sub-models. For example, there is a strong linkage between dispersoids which form during homogenization on subsequent recrystallization behavior after high temperature extrusion or ambient temperature deformation. Finally, a number of observations are presented on the prognosis (opportunities and challenges) for the future of through process modelling.
