Max-Planck-Institut für Eisenforschung GmbH

People have been manufacturing iron for around 19,000 years – yet its possibilities remain far from exhausted. Scientists at the Max-Planck-Institut für Eisenforschung are therefore developing, among other things, new grades of steel that can make car bodies even safer and give car designers greater freedom. Part of what they do involves cooking up and testing new alloys in a lab, reminiscent of a small steel plant. The scientists also investigate ways of preventing corrosion that makes many metallic tools unusable with time. However, their research is not restricted to iron and steel: it also encompasses new alloys, such as titanium alloys for artificial joints. Furthermore, in their search for such new materials, they also develop methods to simulate the behaviour of unknown alloys on the computer.

The Kaiser Wilhelm Institute for Iron Research was founded in 1917, in the midst of the First World War. It was intended to become an innovation laboratory for the German steel industry but morphed into a knowledge center for military technology. Its history illustrates the risk associated with application-oriented basic research in times of economic and political crisis.
Car bodies, aircraft wings or turbine blades – alloys today are customized for any purpose. Roughly 2,500 different types of steel already exist, and that number continues to grow. Jörg Neugebauer and Dierk Raabe, Directors at the Max-Planck-Institut für Eisenforschung in Düsseldorf, are also developing new varieties, and in their search for innovative materials, they even apply the laws of the quantum world.

Materials & Technology

For gourmets, they are mainly a nuisance. For Helge Fabritius, however, they are a treasure trove of information. At the Max-Planck-Institut für Eisenforschung in Düsseldorf, the biologist investigates the construction principles of lobster and crab shells. In the process, he is uncovering how arthropods produce versatile material properties using a very limited choice of basic materials.
Steel used for vehicles should make them light and economical, offer protection in accidents and impose as few limits on designers as possible. Scientists working with Georg Frommeyer create alloys to meet these requirements.

Chemistry Material Sciences Solid State Research

The systematic search of new materials solely based on computers as well as the development of the required highly accurate simulation tools is a major research topic at the MPI für Eisenforschung. In the present article, the approach is introduced using the example of magnetocaloric materials, which are explored to achieve new and energy efficient cooling strategies. For this purpose the complex interaction of two thermodynamic excitation mechanisms – the vibration of atoms in a crystalline lattice and the disorder of magnetic moments – is analyzed and systematically exploited.

Small but strong – Micromechanics of miniaturized materials

2014 Kirchlechner, Christoph; Dehm, Gerhard
Chemistry Material Sciences Solid State Research

Materials of any kind have to endure severe mechanical conditions, which ultimately determine their lifetime. How long can materials sustain cyclic (thermo-)mechanical loading? Is their response independent of material dimensions? Are new mechanisms occurring when the material volume decreases into the nanoworld? Finding fundamental answers to these questions and to use the knowledge to design robust materials is the basic research mission of the new group Nano- and Micromechanics at the MPI of Iron Research.

Why are our cars nowadays still not powered by fuel cells? – One of the main reasons is the degradation of the essential catalysts during fuel cell operation, which leads to a loss of active surface area and thus activity over time. Researchers from two Max Planck Institutes have joined efforts and developed and characterized novel nanostructured materials. A first break-through was achieved with a high-performance electrocatalyst that has demonstrated excellent stability properties. more

Modern steels show a rapid development: 2400 exist already, of which 2000 have been developed during the last decade. Steel grades that are strong and ductile at the same time, are of particular interest for automotive applications. How can a tailored design of such steels be achieved? Which processes occur at the atomic scale? And what is the role of carbon? Scientists at the MPI für Eisenforschung face these challenges with a two-fold strategy by exploiting the principles of quantum mechanics in theoretical as well as experimental methods. more

“The Oxygen Reduction Reaction in the Focus of Interface Chemistry” or “What does Corrosion have in common with Fuel Cells”

2011 Auer, Alexander A.; Biedermann, P. Ulrich; Mayrhofer, Karl J. J.

Whether the future of automotive mobility lies in hydrogen fuel cell technology is still unclear – corrosion, however, is a serious problem in many areas of technology, because not only if you rest, you rust. While the two processes seem very different they have an important chemical reaction in common: the oxygen reduction reaction. At the Max Planck Institute for Iron Research GmbH in Düsseldorf this reaction is investigated in detail within an interdisciplinary project to make fuel cells better and corrosion protection more efficient. more

The free energy of individual crystal structures serves as a key quantity in this context. The present paper discusses the capabilities of modern quantum-mechanical simulation methods in determining these energies. Since it is further demonstrated that even complicated phase transformation sequences can be predicted, these methods open new perspectives for the development and optimization of innovative, tailored materials. more

Ab initio description of iron: Extreme tensile stresses and phase diagrams at finite temperatures

2006 Friak, Martin; Grabowski, Blazej; Neugebauer, Jörg
Material Sciences Quantum Physics
State-of-the-art quantum-mechanical methods have been applied to determine technologically important elastic properties of iron, namely theoretical tensile strength, phonon dispersion, and thermal expansion. These methods allow an accurate and realistic description of material properties without relying on experimental/empirical input parameters. The efficiency of such an approach is demonstrated by studying two key properties of iron: The tensile strength is studied for extreme loads in two different crystallographic directions, [001] and [111]. In the second part, it will be discussed how the methods, which in principle are valid only for T = 0K, can be generalized to study finite temperature properties. more
Advanced NiAl-based high temperature materials are developed and characterized for applications in energy conversion systems. The intermetallic compound NiAl with B2 superlattice structure exhibits superior physical and high-temperature mechanical properties, and excellent oxidation resistance. Disadvantages of polycrystalline NiAl are the lack in plasticity and fracture toughness and room temperature and insufficient high temperature strength at temperatures above 800 °C. The refractory metals Cr, Mo, and Re form with NiAl quasi-binary eutectic systems which enable to produce metal fibres reinforced NiAl-based alloys by using directional solidification. These in-situ composites showing fine-grained and thermally stable microstructures possessing high-temperature strength, superior creep resistence and sufficient room temperature ductility. more

Preparation of Nanostructures from Directionally Solidified Eutectics

2005 Hassel, Achim Walter; Bello Rodriguez, Belen; Milenkovic, Srdjan; Schneider, André
Material Sciences
The production of nanostructured materials is possible by directional solidification. Metals as well as semiconductors can be employed in the eutectics. An appropriate etching allows either the production of short standing wires or of longer wires organised in domains. Furthermore the preparation of isolated nanowires becomes possible by a complete dissolution of the matrix. The system shows a remarkable high degree of order and a uniform crystallographic orientation. Anodic polarisation in a neutral buffer allows a simultaneous passivation of the host phase and selective oxidising dissolution of the wires. Other metals such as gold can be deposited in the so formed cavities. The different strategies for a structuring of these materials and their applications as nanostructured materials and in sensors are discussed. more
Heat-resistant ferritic alloys usually show higher heat conductivities and lower thermal expansions than austenitic ones, which is beneficial for applications in energy conversion units. However, the high-temperature strength of ferritic alloys is lower than that of austenitic ones. Special ferritic iron-chromium and iron-aluminium alloys are strengthened by the formation of intermetallic phases and are optimised with respect to high-temperature strength, formability and corrosion resistance. more
Thin strip casting of steel with a twin roller is a promising development in steel production.
