The first aim of this project is the determination of the strain hardening behaviour of lightweight steels with different material concepts. By using suitable testing methods, the parameters temperature, stress state and strain rate will be considered.
The influence of the phase stability of TRIP- and TWIP-steels on the strain hardening behaviour will also be the focus of interest. The second aim will be the evaluation and the improvement of existing strain hardening models with the obtained results considering the above-mentioned parameters.
The third aim of this project is the identification of microstructures with an extraordinary strain hardening behaviour. By correlating the strain hardening behaviour with the microstructure characteristics, the already existing lightweight steels can be evaluated. By this, the project will contribute to the design of microstructures in new lightweight steels.
