“…The first part is a cross-die component known from [1,3] with a depth of 32 mm, an arm width of 32 mm and an arm length of 30 mm. Within the cross-die component, high local strains can be achieved, which can demonstrate the influence of high degrees of deformation on the microstructure.…”

“…Due to its relatively simpler geometry, this component allows tensile specimens to be taken from the bottom area in order to investigate the mechanical properties after passing through the process chain. Manufacturing via the gas-based forming process is analogous to the previously published work [1][2][3]. After forming, the components are removed from the hot die and quenched in a water bath.…”

“…The EN AW 6010-S aluminum alloy was previously implemented within the gas-based hot sheet metal forming processes, and its ability to be formed into complex laboratory-scale parts is demonstrated in [1,2]. Moreover, in the authors' previous study [3], the high temperature formability of this alloy is characterized in terms of a forming limit curve, which is further validated within a laboratory scale test.…”

Modern hot sheet metal forming processes offer the opportunity, especially in the automotive sector, to meet current demands for ultra-lightweight design. Due to the increased formability at the high process temperatures, high-strength aluminium alloys are increasingly coming into the focus of the industry. However, the complex thermo-mechanical interactions within these processes can lead to undesirable microstructural changes that could have a negative impact on the final mechanical properties. The purpose of this work is therefore to investigate the microstructural evolution of age-hardenable EN AW 6010-S alloy in the course of a modern gas-based sheet metal forming process and to quantify its influence on the resulting mechanical T6 properties. For this purpose, two different components were first formed at laboratory scale and the areas of microstructural interest were identified. Metallographic examinations and EBSD measurements were performed to visualize the influence of process temperature and deformation on the microstructure. EDX analysis helped to identify non-metallic phases. In the next step, artificial aging of the components was performed to increase the mechanical properties. Tensile tests and hardness measurements showed that the deformation and temperature have no negative influence on the final mechanical properties of the alloy.
