| Abstract Scope |
The increasing demand for reliable structural materials in cryogenic applications, such as hydrogen storage and transportation, continues to grow with the transition to a sustainable energy economy. To address this issue, interstitial-alloyed high-Mn austenitic steels were designed and fabricated with an emphasis on balancing cryogenic mechanical performance and cost-effectiveness. Their tensile and impact properties at low temperatures were evaluated, and multiscale microstructural characterization was conducted to investigate the influence of alloying element on deformation and fracture behavior. The observed correlation between cryogenic performance and the deformed microstructure provides insight into the underlying mechanisms, highlighting the potential role of interstitial element in improving mechanical behavior under cryogenic conditions. |
