Hydrogen trapping and embrittlement in metals – A review

open access: yesInternational Journal of Hydrogen Energy
Hydrogen embrittlement in metals (HE) is a serious challenge for the use of high strength materials in engineering practice and a major barrier to the use of hydrogen for global decarbonization. Here we describe the factors and variables that determine HE susceptibility and provide an overview of the latest understanding of HE mechanisms.

Trapping of hydrogen in diamond

Diamond and Related Materials, 1993
Abstract Results are reported from the first studies of isotopically labeled hydrogen incorporated in chemical vapor deposition (CVD) diamond films. Unexpectedly high concentrations of hydrogen were found in both microwave and filament assisted CVD diamond samples when hydrogen (H2) was replaced by deuterium (D2) as the source of atomic “hydrogen” in

Trapped atomic hydrogen

Optical Society of America Annual Meeting, 1991
Atomic hydrogen has been loaded into a 1-K deep magnetic trap through the use of a dilution refrigerator. Evaporative cooling has been used to cool the trapped hydrogen into the submillikelvin temperature regime. These techniques have produced a sample with density of 8 × 1013 cm-3 at a temperature of 100 μK.

Hydrogen Trap in Seashells

ECS Meeting Abstracts, 2016
Hydrogen evolution and adsorption were found that from seashells at high temperature. Large quantities of seashells are abandoned as production waste and it is desired to make use of them. As it is well known that the component of seashell is mostly calcium carbonate CaCO3 layers which are bonded by conchiolin layers.

Hydrogen trapping by TiC particles in iron

Acta Metallurgica, 1984
Abstract The interaction of hydrogen with the interface of TiC inclusion in iron was studied by thermal analysis technique using gas chromatrograph as hydrogen detector. The amount of hydrogen evolved from trap site was measured and its relations with activation energy and trap binding energy were studied.

Dependence of hydrogen trapping densities on hydrogen concentration

Journal of Non-Crystalline Solids, 1991
The diffusive transport of deuterium into various as-deposited, annealed and post-hydrogenated amorphous Si (a-Si) samples is used to determine the effects of hydrogen 4c1oncentration on the trap densities. It is determined that a high H concentration introduces shallow traps for mobile H thus demonstrating that H interact with each other.
