3D atomic analysis of the local chemical composition by atom probe tomography (C08)

• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: from 2011 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 29898171

Project C8 investigates Fe-Mn-Al-C gamma-kappa steels by atom probe tomography (APT) and correlative electron microscopy / APT and will characterize phase fractions, partitioning phenomena, grain boundary segregation, the influence of coherency stresses on composition, the deformation-induced mixing during shearing of the kappa phase and the binding sites of hydrogen.
