Deformation behavior of multi-phase steels (C10*)

• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: from 2015 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 29898171

TP C10 will analyse the effect of chemical composition, grain size and morphology of the microstructure constituents, austenite and martensite, on the active deformation and strain hardening mechanisms in medium manganese steels. A special focus will be placed on the phase boundaries and the relative strengths of both phases. By applying appropriate heat treatments the size, morphology, dispersion and chemical composition of the austenite will be systematically varied based on the compositions which were already analysed within the SFB. By this the respective effects on the deformation and strain hardening mechanisms will be quantified with the aim to tailor the mechanical / technological properties.
