SFB/Transregio 103

From atoms to turbine blades – a scientific basis for a new generation of single crystal superalloys

Welcome to the Collaborative Research Centre SFB/Transregio 103 “From atoms to turbine blades – a scientific basis for a new generation of single crystal superalloys”. The activity is funded by the Deutsche Forschungsgemeinschaft (DFG). The partner universities who collaborate in SFB/Transregio 103 are the Ruhr-Universität Bochum (RUB) and the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU). Three external projects from the Max-Planck-Institut für Eisenforschung (MPIE), the Forschungszentrum Jülich (FZ Jülich) and from the German Aerospace Center (DLR) strengthen the activity.

In SFB/TR 103, different disciplines join forces: processing and manufacturing (melting and casting, additive manufacturing, heat treatment, HIPing), materials testing (elastic constants, creep, high temperature fatigue), advanced materials characterization (SEM, TEM and AP) and scale bridging materials modelling (first principle calculations, phase field modelling, discrete dislocation modelling, finite element analysis). The research in SFB/Transregion 103 tackles two central questions. (1) How do d-shell elements (like Re, Ta and W) affect thermodynamic, kinetic and mechanical properties? (2) How do large (dendrites/interdendritic regions, mm scale) and small scale microstructural heterogeneities (gamma prime particles / gamma channels, mm scale) evolve during processing and creep and how do they affect the material properties?

The SFB/Transregio 103 consists of 22 individual research projects, working in four topical areas (A: Property Assessment, B: Processing and Alloy Development, C: Scale Bridging Materials Modelling, T: Transfer to Industry). Cross sectional research groups ensure that there is a good collaboration between the researchers from these different areas. The first (2012-2015) and second (2016-2019) funding periods were successfully completed. Here we briefly report on the SFB/TR 103 acitivities in its third funding period (2020-2023).
