Abstract Scope There is a growing interest from the aluminium industry in using models with stronger physical basis to both better understand and control the fabrication process and to design products with improved properties. The fabrication chain usually contains several thermo-mechanical steps and the materials properties evolve along the chain due to the action of successive or concurrent physical phenomena, as for instance plastic deformation, recrystallization, or phase transformation. Therefore, any through process modelling approach needs to couple several models, each of them focussing on one phenomenon. As a result errors from each model multiply with each other and, in order to obtain good overall simulation results, accurate individual models, fine tuning, and proper experimental validation are required. In that respect, multi-scales modelling approaches are currently developed to improve the predictive capability of models and to reduce the number of adjusted parameters and experimental input. In this presentation, three examples of such model combinations are given. The first one presents the coupling of a dislocation based model and a crystal plasticity model with a finite element model to simulate warm forming of AA6xxx. In the second example first-principles based calculation results are the input of a mesoscale precipitation model simulating the metastable phases evolution during ageing of AA7xxx. Finally the third example shows how the final microstructure of extruded AA6xxx can be simulated by combining finite element modelling and recrystallization models. Comparison of the simulation results with experiment is presented and used to discuss the relevance and accuracy of such modelling strategies.
