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 Düsseldorf-based Max Planck Institute for Iron Research (MPIE). In its development, the research team has taken into account that steels must now not only be sustainable, strong and formable, but must also be free of critical alloying elements and inexpensive.
"Ultra-high-strength steels are used, for example, in safety-relevant components in power plants, aircraft, industrial plants or even car bodies. There, 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 MPIE. The more energy 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 more tensile and ductile than previous steels. According to the research team, the design strategy developed is compatible with existing industrial processes.
