A4 Investigations of the local alloy composition by means of atom probe tomography
The project A4 deals with the characterization of Ni- and Co-base superalloys by means of atom probe tomography. The main focus of the project lies on the investigation of phenomena, which occur at the (sub-)nanometer scale during high-temperature service of superalloys and which have a significant effect on the properties of superalloys. Such processes include redistribution, segregation and partitioning of solute elements, precipitation of topologically closed packed phases within the γ/γ’-microstructure as well as high temperature oxidation.
