PhD Thesis
Titel: Radiation resistant Al alloys for space applications
In order to reduce CO2 emissions, aluminum and its alloys are increasingly in the focus of attention in lightweight automotive construction. To improve the recyclability of aluminum, so-called “crossover alloys” have been developed. By mixing AlMg (5xxx) with AlZnMg (7xxx) alloy classes, the novel alloys are age-hardenable through precipitation of T-phase (Mg32(Al,Zn)49) and the advantageous properties of both classes are combined. Recent research results showed the irradiation-resistance of the T-phase.
This research investigates the relationship between microstructure and mechanical properties by different heat treatment strategies and, on the other hand, the precipitation sequence of T-phase using differential scanning calorimetry. In addition, two different approaches of manufacturing are investigated: conventional production of the alloy by hot and cold rolling and severe plastic deformation to produce a nanocrystalline microstructure by high pressure torsion (HPT).
