Synergistic enhancement on mechanical properties and corrosion resistance of biodegradable Mg-Zn-Y alloy via V-microalloying

Journal of Magnesium and Alloys
For the sake of improving the mechanical properties and corrosion resistance of biodegradable Mg alloy synergistically, various content of element V (0, 0.05, 0.10, 0.15, 0.20 wt.%) are introduced into an Mg-Zn-Y alloy with long-period stacking ordered ...

Asymmetric charge distribution boosts hydrogen evolution performance in two‐dimensional MoO2/MoS2 step heterostructure

Carbon Energy, Volume 7, Issue 2, February 2025.
This work presents the successful synthesis of a MoO2/MoS2 step heterostructure, revealing that its enhanced hydrogen evolution reaction performance arises from asymmetrically distributed interfacial charges, offering new insights into catalyst design. Abstract Step heterostructures are predicted to hold a profound catalytic performance because of the ...

Limitations of Hydrogen Detection After 150 Years of Research on Hydrogen Embrittlement

Advanced Engineering Materials, Volume 26, Issue 19, October 2024.
This article reviews the phenomenon of hydrogen embrittlement in metallurgy, tracing its historical origins and examining experimental limitations in detecting hydrogen at nanoatomic scales. It evaluates theoretical models and proposes that further development of experimental science is needed to either validate or disprove current HE theories ...

Influence of dislocations on hydrogen diffusion and trapping in an Al-Zn-Mg aluminium alloy

Materials & Design, 2019
Cu-lean Al-Zn-Mg alloys are known to be susceptible to hydrogen embrittlement (HE), which currently limits their use in automotive industry. Several works suggested that the resulting loss of mechanical properties was related to hydrogen trapping in ...

Reduction of Austenite-Ferrite Galvanic Activity in the Heat-Affected Zone of a Gleeble-simulated Grade 2205 Duplex Stainless Steel Weld

, 2019
A Gleeble-simulated microstructure of the heat-affected zone (HAZ) of tungsten inert gas (TIG) welded grade 2205 duplex stainless steel (DSS) has been produced. Local changes in microstructure chemistry were correlated to galvanic activity using scanning
