Hydrogen embrittlement in super duplex stainless steels

, 2019
In super duplex stainless steels (SDSSs), both austenite and ferrite are susceptible to hydrogen embrittlement, however there is a lack of understanding into the effect of hydrogen in each phase.

Hydrogen uptake and embrittlement in nickel-base superalloys during hydrogen flame charging

Communications Materials
Adopting hydrogen as fuel is one of the most promising solutions to eliminate carbon emissions in aviation. However, hydrogen is known to degrade the properties of structural alloys––a phenomenon known as hydrogen embrittlement.

Hydrogen embrittlement and strain rate sensitivity of electrodeposited copper: part I – the effect of hydrogen content

npj Materials Degradation
Slow strain rate tensile testing was conducted on electrodeposited copper, which is a candidate coating material for used nuclear fuel containers. Embrittlement was observed in electrodeposited copper containing 26.4 ± 1.0 ppm hydrogen, with a strain ...
