An experimental-numerical procedure for predicting the recrystallized structure in aluminum extrusion is presented here, altogether with its validation. The whole plan is carried out in three steps: in the first step, the evolution of microstructure of an AA6060 alloy during deformation was studied

The extrusion of a AA6060 round profile was performed on a laboratory 10 MN press to allow grid test analysis. The billet was equipped with 19-rod markers to evaluate the flow path in the container at different strokes. All process parameters suitable for validating FEM simulations (ram load, contai
Three-dimensional finite element analysis using a crystal plasticity constitutive theory was performed to understand and quantify various parametric effects on microstructurally small fatigue crack growth in a AA7075 aluminum alloy. Plasticity-induced crack opening stresses (S o /S max ) were comput
