Fields of Research
The main objective of research is a detailed understanding of the behaviour of metals and alloys under
complex conditions representing those in technical service of engineering materials. For this purpose
engineering materials are subjected to near-service conditions and both the macroscopic and the
microstructural changes are analyzed. The correlation of microscopic processes with the resulting
macroscopic changes in properties are used to obtain information on the relevant mechanisms and
damage processes, in order to develop a better prediction of the application limits and the expected
lifetime of materials under service conditions. The computer-aided description of the material behaviour
based on the occurring physical processes serve for the transfer of the experimentally gained results
to new applications.

Focal points of research activities:
·     Cyclic deformation behaviour of metals (Fatigue of materials, VHCF)
·     High temperature deformation behaviour under cyclic and unidirectional loading
      (Creep, High Temperature Fatigue, Thermomechanical Fatigue)
·     Corrosion behaviour of metallic materials at high temperatures (High Temperature Corrosion)
·     Microstructure/properties optimization
·     Biomechanics
·     Modelling of materials behaviour
