Position resolved damage nucleation and growth at the microstructure length scale (B03)

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

The project focuses on the damage growth at the mcirostructure level, which is primarily influenced by the work hardening capability of the ferrite. A model for isotropic as well as one for latent work hardening will be measured, based on micro pillar compression. The experiments are conducted on ferrite grains of a model material which exhibits the same chemical composition as the ferrite in DP800. Finally, the electrical conductivity and fracture toughness of microstructure constituents (phases, phase- and grain boundaries) will be measured.
