Hydroforming of high-strength aluminium alloys
Third party funded individual grant
Start date : 01.10.2020
End date : 31.03.2023
Project details
Short description
The combination of lightweight material and structural design should enable the manufacturing of components with high specific strengths. Aluminum alloys of the 7000 series are suitable, but they have only a low deformability at room temperature. In this context, heat-assisted process routes for hydroforming are being investigated within the scope of this project, in order to generate geometrical complex tube profiles. For this purpose, material models as well as process simulations of different heat treatment strategies will be created and validated. Based on this, the forming process will be designed and a demonstrator geometry will be produced. Finally, relevant process windows will be determined by varying the geometry and process parameters.
