Experimental and model-based characterization of the strength, deformation and failure behavior of new TRIP steel variants and TRIP-Matrix-Composites (B02)

• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: from 2008 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 54473466

TP B2 investigates the strength, deformation and failure behavior of the cast alloys as well as the steels and composites of the powder metallurgical processing route. Purpose is the comprehension of the correlations between initial microstructure, mechanical properties and deformation induced microstructure changes in the steel, the composites and the gradient materials under uni- and multiaxial stresses as well as the modeling of the material behavior. This will be done via quantitative description of the relevant work hardening mechanisms. The deformation mechanisms will be identified and quantified by using the in situ X-ray diffraction technique.
