Permeation of Hydrogen in Palladium

open access: yesMaterials Transactions, JIM, 1993
Experimental studies on the permeation of hydrogen in a palladium plate 1-2×10 -4 m in thickness were carried out at a constant temperature under the application of a constant hydrogen pressure in the respective ranges from 261 to 191 K and from 66.5 to 2660 Pa. Hydrogen permeabilities obtained in the permeation experiment are expressed by the formula

Evaluation of hydrogen permeation rate through zirconium pipe

open access: yesNuclear Materials and Energy, 2018
To launch a fusion reactor stably, it is necessary to prepare sufficient amount of tritium by an external tritium source. Tritium production using nuclear reactions by neutron and Li in a high temperature gas-cooled reactor (HTGR) is an attractive method.

Understanding the interaction between a steel microstructure and hydrogen [PDF]

open access: yes, 2018
The present work provides an overview of the work on the interaction between hydrogen (H) and the steel’s microstructure. Different techniques are used to evaluate the H-induced damage phenomena. The impact of H charging on multiphase high-strength

The impact of hydrogen on the ductility loss of bainitic Fe–C alloys [PDF]

open access: yes, 2016
The influence of hydrogen on the mechanical properties of generic lab-cast Fe-C bainitic alloys is studied by tensile tests on notched samples. The bainitic microstructure is induced in a 0.2% C and 0.4% C Fe-C alloy by an appropriate heat treatment. The
