Abstract (technical / expert description):

The
use of Tailor Heat Treated Blanks (THTB) enables the forming of
high-strength aluminum components at room temperature. A local
adaptation of the material properties is possible by local short-term
heat treatment performed by laser heating. As a result, the local
forming behavior of the components can be adapted to satisfy specific
forming requirements.


The
aim of this research project is the identification and qualification of
heat treatment strategies for the distortion-free heat treatment of
precipitation-hardenable aluminum alloys of the 7000-series in the THTB
process. Essential preconditions for reproducible forming of components
are undistorted sheets. For this purpose, temperature-dependent material
properties are first determined and then transferred into a
thermo-mechanically FE model. Based
on the experimental and numerical results, a demonstrator component is
thermally treated by using locally adapted heat treatment layouts and
then produced by forming.
