โœฆ Synopsis

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 by means of small-scale laboratory test, the processing parameters being chosen in order to reproduce the typical industrial conditions. In the second step, the analysis of microstructure evolution after the heat treatment (550 โ€ข C for 30 min and 180 โ€ข C for 10 h) was analyzed, the obtained informations being used in order to fit a recrystallization model to be implemented inside the Deform FEM code environment. Finally, in the third step, the obtained informations are applied to extrusion tests presented in another papers by the

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
