The hydrogen embrittlement of 12Cr2Mo1R(H) steel at different strain rates were investigated after hydrogen precharging for 4 h in a 0.5 M H 2SO 4 solution with 2 g/L ammonium thiocyanate. Results showed that the embrittlement index increased and gradually reached a relative stable An investigation into the hydrogen embrittlement An investigation into the hydrogen embrittlement susceptibility of experimental 304 stainless steel alloys modified with ruthenium and palladium additions. University of Birmingham. Ph.D. Atomistic investigation of hydrogen embrittlement effect Feb 15, 2019 · As hydrogen has such an acute impact on material fracture characteristics, it is very necessary to study the hydrogen-induced intergranular fracture mechanism to prevent and control hydrogen embrittlement . Experiments are usually limited in evaluating hydrogen segregation near GBs due to complex local atomic structures and the hydrogen mobility.
The problem of hydrogen embrittlement in the traffic and energy sector is becoming increasingly important as hydrogen is viewed as an important energy carrier of the future. The associated development of new technologies to manufacture, distribute and use hydrogen as an energy supplier requires the qualification of available raw materials and Investigation of Hydrogen Embrittlement Susceptibility and Apr 20, 2020 · View 1 peer review of Investigation of Hydrogen Embrittlement Susceptibility and Fracture Toughness Drop after in situ Hydrogen Cathodic Charging for an X65 Pipeline Steel on Publons Download Web of Science My Research Assistant :Bring the power of the Web of Science to your mobile device, wherever inspiration strikes. Investigation of Hydrogen Embrittlement of High Strength Mar 26, 2017 · The uptake and diffusion of hydrogen in the steels under different cathodic protection levels were analyzed by hydrogen permeation test and hydrogen content measurement. Slow strain rate testing (SSRT) under cathodic conditions as well as mechanical performance degradation testing after long term immersion were used to determine the hydrogen embrittlement (HE) susceptibilities
Investigation of hydrogen embrittlement in high Mn steels using multiscale approach High-Mn steels are next generation alloys for highly demanding load bearing applications with potentially high benefit for automotive and structural parts, thus their hydrogen embrittlement susceptibility is a topic Investigation of mechanical tests for hydrogen Abstract:the problem of hydrogen embrittlement in Ultra High Strength Steels is well known. Slow Strain Rate, Four Points Bending and permeation tests were performed with the aim of characterizing innovative materials with an ultimate tensile strength higher than 1000 MPa. The Investigation of the Hydrogen Embrittlement Susceptibility Dec 05, 2019 · The aim of the present study is the investigation of hydrogen embrittlement in two welded aluminum alloys with different microstructures, that is the AA5083-H111 alloy and the AA6082-T6 alloy. The former belongs to the category of non-heat-treatable aluminum alloys, while the latter belongs to that of heat-treatable aluminum alloys.
Jul 31, 2019 · Hydrogen embrittlement is a phenomenon of material degradation present in many engineering materials (metals and alloys) working under aggressive environments, thereby promoting fracture and compromising their structural integrity at both the macro- and micro-levels.
