We investigate the effect of manufacturing processes and operational loads on the microstructure and the internal stress in materials and components. A particular focus lies on the identification of the combinatory degradation mechanisms of high temperature corrosion, stress corrosion cracking and hydrogen embrittlement. This is done using experimental methods, such as permeation tests with superimposed mechanical loads, and numerical methods, such as the simulation of microstructure and internal stress formation. This lays the basis for the appropriate selection of materials or the optimization of materials and processes and the prediction of operational behavior.
