Abstract: Since 2007 the Collaborative Research Center CRC 761 “Steel ab initio – quantum mechanics guided design of new iron-based materials” works on a mechanism-driven material development using the example of high Mn steels. After the successful approval for the continuation of the project by the Deutsche Forschungsgemeinschaft, the collaboration of scientists and engineers of the RWTH Aachen University and the Max Planck Institut für Eisenforschung in Düsseldorf will continue in the third funding phase from July 2015 to 2019. In 17 part projects and two transfer projects involving industrial partners diff erent topics of materials design are handled. After successful finishing of the project the serious progress in development of structural materials and processes for their fabrication is expected. In particular, the experimental and numerical methods for prediction of steels are created; the structure of these steels is directly forming at nanometric level. It is important in this connection to conduct transformation of overcooled austenite at very low temperatures and in the conditions of mechanical effect. The achieved combinations of mechanical properties exceed substantially the requirements for up-to-date steels due to high density of defects and local difference in chemical composition.
