Abstract
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.
