Finite element modelling of microstructural changes during equal channel angular drawing of pure aluminium

Abstract Grain refinement by severe plastic deformation (SPD) techniques, as a mechanism to control microstructure (recrystallization, grain size changes,…) and mechanical properties (yield strength, ultimate tensile strain, hardness variation…) of pure aluminium conductor wires, is topic great interest for both academic industrial research activities. This paper presents an innovative finite element (FE) model able describe the microstructural evolution continuous dynamic recrystallization (CDRX) that occur during equal channel angular drawing (ECAD) commercial 1370 (99.7% Al). A user subroutine has been developed based on continuum Hall-Petch (H-P) equations predict variation change. The validated comparison with experimental results predictive analysis conducted varying die angles. study provides accurate prediction thermo-mechanical phenomena process characterized large deformation.
