The Materials and Corrosion Group headed by Uwe Köster is in general concerned with the analysis of the microstructure of metastable materials, especially metallic glasses, nano- and quasicrystalline alloys, as well as advanced Mg- and Ti-alloys, the analysis of their thermal stability and in particular their environmental properties. These investigations are going to fill up the gaps in the comprehension of the microstructure/property relation, which is essential in order to design materials with properties beyond present limitations. Recent and current projects include:

  • Design of novel microstructures, e.g. nanocrystalline alloys obtained by crystallizing glassy precursor 
  • Hydrogen induced plasticity of Ti- and Fe-alloys 
  • Environmental properties of titanium 
  • Oxidation and corrosion of magnesium alloys 
  • Hydrogenation of nanocrystalline magnesium and magnesium alloys 
  • Hydrogenation and oxidation of bulk metallic glasses, nano- and quasicrystalline alloys 

Within the Mg Hydrides network, Dortmund is offering training at the postgraduate and postdoctoral levels. The training can include:

  • Electrochemical hydrogenation and corrosion 
  • Metastable phase transformations (induced by hydrogenation or corrosion)
  • Microstructural characterization (XRD, TEM, SEM) 

Within the Network, Dortmund is leading Task-Force IV on "Electrochemical Insertion Kinetics", and is a participant in Task-Force II "Alloy Design and Thermodynamics" and in Task-Force VI "Structural Characterization". The research focuses on investigating the microstructural/chemical properties relationship in regard to the hydrogenation behavior of nanocrystalline Mg with and without Nb2O5.
