Niobium cathodic cage duplex treatment is applied to VP20TS steel to evaluate the influence of surface roughness and temperature on coating performance. Results show that higher temperatures promote thicker nitride layers and increased microhardness, while finer surface preparation enhances adhesion and wear resistance, revealing optimal conditions for

This review's second part details the mechanical, corrosion, and electromagnetic behaviors of FSSs. It integrates the foundational microstructure (texture/defects/precipitates) and processing effects from Part I to establish and analyze complex property–property interrelationships critical for high‐performance applications.

Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

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.
