Steel‐supported, PGM‐free NiMo cathodes and anodized Ni‐coated steel anodes enable an ionomer‐free anion exchange membrane water electrolyzer. The fully noble‐metal‐free single cell delivers 1 A cm−2 at 1.92 V in 1 M KOH (60 °C) with stable operation over 60 h under dynamic conditions, demonstrating a scalable approach to cost‐effective green hydrogen ...

The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Precipitation‐modulated recrystallization enables a programmable bimodal harmonic architecture in a high‐entropy alloy, delivering 1–2 GPa yield strength with >10% ductility from −196 °C to 700 °C. The resulting broad‐temperature robustness arises from the synergy of dual‐mode nanoprecipitation, harmonic core–shell topology, and temperature‐adaptive ...

The billet is pierced and rolled continuously forward in a spiral under the tandem skew rolling process, which could be divided into three stages: single piercing, TSR, and single rolling. Force equilibrium and rotation conditions for the forming coordination of each rolling stage are calculated and obtained, whereas the experimental research was ...

Mixing Behavior of Natural Gas and Hydrogen in a High‐Efficiency Vane (HEV) Static Mixer
Static mixers play a crucial role in the safe transport of hydrogen‐blended natural gas. Computational fluid dynamics (CFD) was employed to investigate the effects of structural parameters of the HEV static mixer on the mixing behavior and homogeneity of natural gas and hydrogen. The modeling approach was well validated against experimental data.

The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these

ABSTRACT Fe‐Cr‐Ni‐Cu alloy has been extensively utilized over the past few decades due to its low cost yet high strength. Nevertheless, the poor ductility of this alloy limits its real application in industrial fields. In this study, a soft Fe‐Cr‐Ni alloy was combined with a Fe‐Cr‐Ni‐Cu alloy by laser‐directed energy deposition (LDED) to fabricate the ...
