Investigation of the Plane Strain Behaviour of a Laser-Heat Treated Aluminium Alloy

The necessity of complex-shaped components characterized by superior mechanical properties and limited weight is moving the attention to Aluminium (Al) alloys. Deep Drawing Steel grades possess stamping characteristics formability with respect Al But need light-weighting pushes towards adoption materials optimal strenght-to-weight ratio, like Todays alloys are certainly used in transport sector but their (at room temperature) poorer than grades, which still hinders massive implementation forming processes drives research toward innovative manufacturing solutions. One most promising approach overcome such a limitation and, thus, manufacture complex component using cold processes, local heat treatments obtain suitable distribution material able enhance at temperature.The design locally modified blanks needs: (i) an extensive investigation behaviour temperature after heating (ii) Finite Element approach. As for former aspect, authors proposed fast comprehensive methodology investigate hardening alloy (AA5754-H32) annealed laser treatment. Using similar approach, model was then enriched considering normal anisotropy, evaluating correlation between Lankford parameter condition reached end To improve knowledge on plastic response material, present work focusses characterization plane strain behavior AA5754, initially wrought (H32) subsequently heating. In particular, study proposes new quasi-homogeneous specimen combines profile optimized geometry produce prevailing heat-treated zone. way, data about could be obtained large range conditions determined preliminary
