High manganese steels (HMnS) represent a highly fascinating class of alloys within the field of advanced high strength steels. During the last decades, HMnS have gained a lot of attention in both academic and industrial research, mainly due to their outstanding mechanical properties. Therefore, potential fields of industrial application supposedly extend from chassis components in the automotive industry over equipment for low-temperature applications to forgings with alternative process routes. Usually, these steels contain manganese contents well above 3 mass%, along with significant alloying with carbon and aluminium.
The plasticity of HMnS is strongly influenced by their low stacking fault energy. Consequently, the low dynamic recovery rate in combination with the activation of additional deformation mechanisms, i.e., twinning-induced plasticity (TWIP), transformation-induced plasticity (TRIP), and microband-induced plasticity (MBIP), promote high work-hardenability. That results in a combination of high ultimate tensile strength (often above 1 GPa) and high uniform elongation (often above 50%). In order to take full advantage of the potential of HMnS, a description of these mechanisms in predictive, physics-based models is required. However, such descriptions constitute a formidable scientific challenge due to the microstructural modifications at various length scales, as well as complex chemical interactions.
The processing of HMnS requires careful consideration of solidification conditions in order to minimize segregation and control precipitation and microstructure development. The further fabrication via rolling, annealing, cutting, and machining needs to be adopted to the specific material behaviour.
Careful review of the related literature at present revealed that there is still a severe need to better understand the physical metallurgical mechanisms of HMnS. Relevant aspects include but are not restricted to microstructure evolution during deformation and annealing, the role of interfaces, hydrogen embrittlement and management, advanced processing techniques, and multi-scale strain-hardening engineering. Both advanced experimental as well as numerical approaches, including first-principle calculations, are necessary for an increased understanding and future development of HMnS. Comprehensive fundamental research on these topics often necessitates interdisciplinary collaboration of materials scientists, physicists, chemists, and engineers.
It is my pleasure to invite you to submit original contributions to this Special Issue that may take into account any of the materials aspects mentioned above.
