TRR 103: From Atoms to Turbine Blades – Scientific Framework for a New Generation of Single-Crystal Superalloys

Type of Funding: DFG Programmes, Collaborative Research Centres


Turbine blades in gas turbines are as indispensable for keeping modern society moving as they are for providing a steady, sustainable supply of electricity. Aside from their use in energy production, gas turbines are also employed in aviation. The key materials for these turbine blades are so-called monocrystalline superalloys – alloys based on nickel.

In order to achieve both a higher degree of efficiency and greater sustainability with these superalloys, the collaborative research centre project SFB/Transregio 103 “From atom to turbine blade – scientific foundations for a new generation of monocrystalline superalloys” is investigating completely novel monocrystalline technologies.

Fundamental questions lie at centre of the research – for example, questions concerning which structural formation processes occur during the production of components, and whether the application of high temperatures will cause microstructures to disintegrate (degradation). SFB/TR 103 brings together researchers from the fields of materials science and engineering, solid state physics and chemistry, and cross-scale material modelling and production engineering.

SFB/TR 103 is based at RUB (coordinating institution) and at the University of Erlangen-Nürnberg. The German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt – DLR), the Helmholtz Research Centre Jülich, and the Max Planck Institute for Iron Research are participating in the project as well.
