Investigation of the local alloy composition by atom probe tomography (A04)

• Subject Area: Thermodynamics and Kinetics as well as Properties of Phases and Microstructure of Materials
• Term: from 2012 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 190389738

In the third funding phase of the SFB/TR 103, the project A4 focuses on the application of atomic probe tomography to study the local composition of phases in alloys. Project A4 will use the newly developed protocol to produce samples with targeted defects using advanced electron microscopic techniques. Project A4 Measurements to characterize with atomic resolution the distribution of different alloying elements to specific defects arising during creep deformation in Co-based and Ni-based alloys and to interpret the observed microstructure.
