The Influence of a Local Heat Treatment on the Drawing Properties of an Aluminium Alloy 2001-01-3376

By forming complex components a combination of deep drawing and stretch drawing is incidental. To investigate the possibilities of local heat treatment on a stretch drawing process an experimental setup for the stretch drawing of a cylindrical cup using an elastomer membrane was made. The local heat treatment of the aluminium alloy AA 6016 T4 was conducted by an electrical heated copper punch. The results of experimental investigations were confirmed in FE-calculations, which show an increase of the stretch drawing depth and a change in the anisotropic behaviour of the material due to the heat treatment.
