Review of Characterization on Hydrogen Embrittlement by Micro-Sample Testing Methods
Metals, 2023 Conventional-sized specimens have been well and widely applied in research on hydrogen embrittlement. However, when the limited-size core components (nozzles and valves, etc.) of hydrogen energy equipment are evaluated for service damage, traditional ...

Review of Hydrogen Embrittlement in Metals: Hydrogen Diffusion, Hydrogen Characterization, Hydrogen Embrittlement Mechanism and Prevention [PDF]
Acta Metallurgica Sinica (English Letters), 2020 Hydrogen dissolved in metals as a result of internal and external hydrogen can affect the mechanical properties of the metals, principally through the interactions between hydrogen and material defects. Multiple phenomena such as hydrogen dissolution, hydrogen diffusion, hydrogen redistribution and hydrogen interactions with vacancies, dislocations ...

Effect of Pre-strain on Hydrogen Embrittlement in Intercritically Annealed Fe-6.5Mn-0.08C Medium-Mn steels [PDF]
Archives of Metallurgy and Materials, 2022 The present research deals with the effect of pre-strain on the hydrogen embrittlement behavior of intercritically annealed medium-Mn steels. A slow strain-rate tensile test was conducted after hydrogen charging by an electrochemical permeation method ...
