A new design strategy for processing medium manganese steel with improved properties has now been developed by a research team, mainly from China's Northeastern University and the Max Planck Institute for Iron Research (MPIE) in Düsseldorf. During development, the research team took into account the fact that steels now not only have to be sustainable, strong and malleable, but also have to do without critical alloying elements and be inexpensive.
"Ultra-high-strength steels are used, for example, in safety-relevant components in power plants, aircraft, industrial plants and car bodies. Here, the steels must be strong, but at the same time be able to absorb a high level of energy in the event of deformation," explains Professor Dierk Raabe, Director at the MPIE. The more energy is absorbed, the better the impact is attenuated and the occupants remain protected.
The new medium manganese steel has been optimized using various measures to make it stronger and more ductile than previous steels. According to the research team, the design strategy developed is compatible with existing industrial processes.
