Notes:
The microstructure in heavily deformed metals can be characterized as a complex“mixture” of low and high angle boundaries. By careful annealing of such cold deformedconditions, ultra-fine grained materials can be obtained. This phenomenon has been known for longand utilised in the production of special aluminium sheet qualities, and has received new interestwith the emergence of the equal channel angular pressing (ECAP) technique. This work reviews themechanical properties resulting from plastic deformation and annealing of aluminium, looking atalloys which prior to annealing was subjected to both severe plastic deformation (ECAP) and moreconventional deformation by cold rolling. The effect of the resulting microstructures on thesubsequent work hardening properties are model, applying the new microstructural metal plasticitymodel (MMP-model) developed in Trondheim over the last decade
