Nanostructured steel crystallization [PDF]
Литьë и металлургия, 2022 Steel crystallization has been shown to be a nanostructured process. Austenite microcrystals in liquid steel with a carbon concentration of 2.5 to 9 atomic percent, δ‑ferrite microcrystals in melt with a carbon concentration of up to 2.5 atomic percent ...

Gradient nanostructured steel with superior tensile plasticity. [PDF]
Sci Adv, 2023 Nanostructured metallic materials with abundant high-angle grain boundaries exhibit high strength and good radiation resistance. While the nanoscale grains induce high strength, they also degrade tensile ductility. We show that a gradient nanostructured ferritic steel exhibits simultaneous improvement in yield strength by 36% and uniform elongation by ...
