In order to ensure the efficient development of complex novel steels, bulk metallurgical high throughput methods are developed and deployed at the Max-Planck-Institut für Eisenforschung within the group "Combinatorial Metallurgy and Processing", for example for innovative weight-reduced steels. more

Employing ab initio based multiscale simulation methods, fundamental deformation mechanisms in complex materials can be predicted as function of the alloy composition and the process parameters. The performance of these methods is demonstrated for high-Mn steels, which can have an ultimate tensile strength above 1 GPa and up to 70% elongation. more

Materials that can heal themselves in the event of mechanical damage offer enormous potential. Research and development in the field of polymer materials is the most advanced here. The Max-Planck Institut für Eisenforschung (MPIE) is working on the realization of self-healing also for metallic alloys. more

Due to their mechanical properties, dual-phase steels are used in automotive applications for safety-relevant parts. Though representing the first high strength steels applied in large scale, their potential is still not fully exploited. Therefore, the Max-Planck-Institut für Eisenforschung investigates the damage mechanisms of these steels. more

New materials which are based on intermetallic phases and which are specifically suited for applications at high temperatures in corrosive environments are developed at the Max-Planck-Institut für Eisenforschung in the group “Intermetallic Materials“. One example are iron aluminide (Fe–Al) alloys, which can be a cheap alternative to high-alloyed steels. more

At the Max-Planck-Institut für Eisenforschung in Duesseldorf, materials simulation experts work hand in hand with characterization experts in order to shift the boundaries of our knowledge steadily to scales down to individual atoms. In this way, it was recently possible to decipher the strengthening effect of k-carbides in high-manganese steels. more

Though it is hard to determine the local distribution of the smallest element hydrogen in microstructures of steels, it can have a dramatic impact on their properties. Combining modern simulation and characterization tools, the Max-Planck-Institut für Eisenforschung is working on solutions for this dilemma. more

Cold drawn pearlite wires exhibit the highest strength among all industrial mass materials. But this nominally simple system can also surprise fundamental research with a totally unexpected behaviour. How severe plastic deformation at room temperature can induce nanoscaled martensite was investigated by an interdisciplinary team of the Max-Planck-Institut für Eisenforschung . more

Medium manganese steels exhibit an enormous potential to create microstructures leading to high strength, ductility and toughness at acceptable costs. At the Max-Planck-Institut für Ei­senforschung relevant mechanisms were elucidated to enable a knowlegde-based design of new medium manganese steels and corresponding processing parameters. more
