Role of Vanadium Carbide in Hydrogen Embrittlement of Press-Hardened Steels: Strategy From 1500 to 2000 MPa

open access: yesFrontiers in Materials, 2021
This work investigated hydrogen trapping and hydrogen embrittlement (HE) in two press-hardened steels, 22MnB5 for 1,500 MPa grade and 34MnB5V for 2000 MPa grade, respectively.

Effect of cathodic hydrogen charging on the surface of duplex stainless steel [PDF]

open access: yes, 1993
The effect of cathodic hydrogen charging on the mechanical properties of steels has been extensively investigated (1-5). There is a general agreement, that cathodic harging during a tensile test leads to reduction in ductility, and embrittlement (5-7 ...

Study on the Influence of Surface Integrity on Hydrogen Permeation Resistance of Hydrogen Production Reactor Materials

open access: yesApplied Sciences, 2023
Hydrogen permeation reduces a material’s properties and increases the risk of brittle fracture, which causes a potential safety hazard. A workpiece’s hydrogen permeation resistance could be improved by improving its surface integrity through surface ...

Car park charging in the Cairngorms National Park [PDF]

open access: yes, 2006
Charges for parking in the countryside pose a particular dilemma in Scotland as they are seen by many outdoor groups as a backdoor approach to restricting the public's newly acquired right of responsible access to the countryside.

Electrochemical cell recharging by solvent separation and transfer processes

open access: yesScientific Reports, 2022
Electrochemical conversion and storage of unutilized renewable energy will contribute to decarbonization. Here, we create the concept of a liquid electrochemical cell that discharges between the anodic and cathodic sides by reverse reactions of the same ...
