Microstructure mechanics and fundamentals of twinning in the alloy system Fe-Mn-Al-C (A07)

• Subject Area: Metallurgical, Thermal and Thermomechanical Treatment of Materials
• Term: from 2007 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 29898171

The long term goal of part project A7 is the development of a systematic scale bridging approach for modeling the micro mechanics of multi-phase materials using ab initio data. To achieve this a constitutive model for TWIP/TRIP materials has been developed based on the underlying physical phenomena. The focus of the third period of the proposal will be to include the effect of hydrogen on the plastic behavior as well as studying in detail the interaction between the different phases of multi-phase materials.
