Hydrogen embrittlement in metallic nanowires. [PDF]

open access: yesNat Commun, 2019
AbstractAlthough hydrogen embrittlement has been observed and extensively studied in a wide variety of metals and alloys, there still exist controversies over the underlying mechanisms and a fundamental understanding of hydrogen embrittlement in nanostructures is almost non-existent.

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 ...
