High-strength Al alloys of the 7xxx series are promising candidates for further light-weighting of car bodies. However, they are difficult to process by extrusion: complex geometries in particular pose a major challenge due to high extrusion pressure

Al-Mg-Si alloys are an important class of Al wrought alloys. Further increasing their strength has significant economic potential. Previous approaches were focusing on increasing the amount of the main hardening elements Mg and Si, adding Cu and Zn f

In industrial practice, no sensors capable of obtaining microstructural information in situ during thermo-mechanical processing of Al alloys are commonly employed. Inductive electrical conductivity measurement is safe, inexpensive, and capable of acq

Dissimilar welding of Ti and Al alloys is challenging due to the potential formation of brittle intermetallics, which can compromise weld strength. Friction stir welding (FSW) is an advanced joining method with the potential to drastically reduce or

Two-step ageing of 7xxx series alloys can reduce ageing time while obtaining similar mechanical properties as a longer isothermal heat treatment. In this paper, an intermediate deep-drawing step at 120–160 °C is introduced to produce elongated cup

Room-temperature cyclic deformation of age-hardenable alloys can produce similar strength as artificial ageing in much shorter time, but industrial applicability is limited due to the high number of required cycles. As an alternative, fewer cyclic de

Aluminium alloys of the 7xxx series are attracting the attention of automakers due to their high specific strength. However, widespread use of 7xxx series alloys for the production of car parts from sheet metal has so far been prevented due to their

Due to their high specific strength, EN AW-7xxx aluminium alloys are promising materials for reducing the weight of automotive structural parts. However, their formability at room temperature is poor due to pronounced natural ageing. Therefore, we in
