Selected Research Projects

Articles in "stahl und eisen"

Selected research projects are presented here. They were published in the journal "stahl und eisen" during the 100-years celebrations of the Institute 2017. The full articles are only available in German. The respective contact persons can give you further information though.
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.

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.

Werkstoffe, die sich bei mechanischer Beschädigung selbst heilen können, bieten enormes Potential. Am weitesten fortgeschritten ist hier die Forschung und Entwicklung im Bereich der polymeren Materialien. Das Max-Planck-Institut für Eisenforschung (MPIE) arbeitet daran, Selbstheilung auch für die Anwendung metallischer Werkstoffe zu realisieren.

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.

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.

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.

Light-weight high manganese steels: Progress through atomistic understanding

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.

Detection of hydrogen traces in steels

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 .

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.

Corrosion is what usually determines the lifetime of a component. The development of novel advanced strategies for corrosion protection requires an in depth understanding of the underlying mechanisims. This also a prerequisite for a reliable prediction of corrosion damage. The Max-Planck-Institut für Eisenforschung takes a lead.
