Mechanisms and statistics of deformation induced damage as a function of load path and microstructure (B02)

• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 278868966

In the second funding period a 3D analysis of the microstructural damage in DP800 will be conducted to determine the mechanisms operating in the bulk (AP1). In addition, the evolution of damage and the interaction of damage mechanisms will be investigated with respect to variations in the microstructure and load path (AP2-3). Moreover, the developed method of automated damage analysis in DP800 will be extended to 16MnCrS5 (AP4). The respective micromechanical characterization at room temperature will also be extended to elevated temperatures (AP5). Furthermore, the work program includes an experimental validation of damage-tolerant microstructures designed in cooperation withproject partners.
