This development is focusing on one of the most complex and important production steps of flat rolled products that is the simulation of hot rolling. During hot rolling two phenomena, work hardening and the process of regeneration of microstructure have strong influence for physical properties of aluminium alloys. Dynamic recovery has importance in the dynamic softening beside dynamic recrystallization in aluminium alloys. Hot rolled and newly modified grain structure is influenced by these dynamic phenomena. Hot rolled grain structure goes through significant changes under further production steps like cold rolling and heat treatments. But aside from these intermediate production steps the microstructure that we get after hot rolling has significant effect on mechanical and grains structure of the final flat rolled product. Proper cellular automata simulations of recrystallization and recovery can be the basis for good technology planning practices.

The softening of Al-Mn base alloys not only depend on the degree of deformation and the parameters of annealing, but the pre-treatment of as-cast alloy. Large extent of the Mn remains in the solid solution during the crystallization process. During a high temperature heat treatment the manganese precipitate from the solid solution phase. The size and amount of the precipitations mainly of the processes takes place during annealing. In this article this effect is studied through the heat treatment and deformation of a specific alloy.
