The effect of plastic deformation on hydrogen diffusion in nickel Alloy 625
Lu, Xu; Díaz, Andrés; Ma, Jun; Wang, Dong; He, Jianying; Zhang, Zhiliang; Johnsen, Roy (Peer reviewed; Journal article, 2022)Recently, several hydrogen-assisted failures have been reported on different nickel alloys used in the subsea oil and gas industries. It is thus essential to correlate hydrogen uptake and diffusion behavior with stress ... -
Experimental and numerical study on hydrogen-induced failure of X65 pipeline steel
Lin, Meichao; Yu, Haiyang; Wang, Dong; Díaz, Andrés; Alvaro, Antonio; Olden, Vigdis; Koren, Erik Aas; Ding, Yu; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2024)Hydrogen-induced fracture of X65 pipeline steel under in-situ electrochemical charging is investigated by using in situ slow strain-rate tensile (SSRT) test, hydrogen diffusion test, fractography analysis, and finite element ... -
Investigation of hydrogen embrittlement behavior in X65 pipeline steel under different hydrogen charging conditions
Wang, Dong; Hagen, Anette Brocks; Undrum Fathi, Pernille; Lin, Meichao; Johnsen, Roy; Lu, Xu (Journal article; Peer reviewed, 2022)The hydrogen effect on a X65 carbon steel was investigated by tensile tests under both ex-situ and in-situ hydrogen charging conditions. The fractured samples were characterized and compared using a combination of scanning ... -
Understanding the hydrogen effect on pop-in behavior of an equiatomic high-entropy alloy during in-situ nanoindentation
Wang, Dong; Lu, Xu; Lin, Meichao; Wan, Di; Li, Zhiming; He, Jianying; Johnsen, Roy (Peer reviewed; Journal article, 2021)The variations in the pop-in behavior of an equiatomic CoCrFeMnNi high-entropy alloy under different hydrogen charging/discharging conditions were characterized via in-situ electrochemical nanoindentation. Results show ...
