In the course of lightweight construction, modern materials with high
strength and low density are essential. High-strength aluminium alloys
such as 7000 series aluminium alloys meet these requirements but are
only limited formable at room temperature. Thus, different heat assisted
sheet metal forming processes are used to increase the formability.
First investigations on the highstrength aluminium alloy AA7075 show a
temperature-dependent and tensilecompressive asymmetric material
behaviour. Since both tensile and compressive forces occur in sheet
metal forming processes, an understanding of temperaturedependent
tension-compression asymmetry is vital to set up material models for
process design. Until now, the tension-compression asymmetry has barely
been investigated for high-strength aluminium alloys at different
temperatures. Therefore, further experimental studies are necessary.
Within this contribution, the material behaviour of AA7020-T6 and
AA7075-T6 is hence examined under uniaxial tensile and compressive load
at different temperatures. For this purpose, both tensile and
compressive tests are carried out on flat specimens between room
temperature and 200 °C.
