A comparison of internal hydrogen embrittlement and hydrogen environment embrittlement of X-750 [PDF]

open access: yesEngineering Fracture Mechanics, 1999
Hydrogen has been shown to degrade the mechanical properties of nickel-base alloys. This degradation occurs whether the material is in a hydrogen producing environment or if the material has dissolved hydrogen in the metal due to prior exposure to ...

Research on Mechanism of Methanol–Hydrogen Co-Transport Inhibiting Hydrogen Embrittlement in Pipeline Steel

open access: yesMetals
Existing studies suggest that hydrogen embrittlement will occur in pipeline steel under a hydrogen environment, and gas is often used as a hydrogen embrittlement inhibitor. As one of the most effective hydrogen carriers, methanol may competitively adsorb

The Phenomenon of Hydrogen Embrittlement in High-Strength Bolts [PDF]

open access: yesArchives of Metallurgy and Materials, 2023
The hydrogen embrittlement of metals is caused by the penetration and accumulation of hydrogen atoms inside the metal. The failure of the product due to hydrogen embrittlement is delayed in time and does not occur immediately after its manufacture, but ...
