“…However, the hydrogen influence on the strength is not clear yet. Different studies have shown different effects including both hardening [37,38] and softening [39,40]. But a common agreement has not been reached yet.…”

“…The ductile fracture characteristics of the specimens in this state almost disappear. As reported in [4] , a large amount of H generated by the cathodic reaction will be adsorbed on the surface of the sample, then the H atom will diffuse into the sample and enrich at the crack tip. The aggregated hydrogen atoms will reduce the binding force of the Fe-Fe bond and will further cause hydrogen embrittlement at the microscopic level.…”

Hydrogen-induced delayed cracking is an important factor leading to the failure of ultra-high strength steels during service, thus in this study, the mechanical properties and hydrogen trapping of hot formed 22MnB5 steel considering different content of V (0, 0.05, 0.09 wt.%) and corresponding microstructure were investigated. Slow strain rate tensile tests (SSRT) were applied to obtain the tensile strength and elongation of samples under different medium conditions (air, HCl immersion and electrolytic hydrogen charging). Besides, microstructure and atomic distribution morphology of the samples were detected and analyzed by transmission electron microscope (TEM) and atomic probe tomography (APT) technique. Results showed that both resistances of hydrogen-induced delayed cracking in MnB-V5 and MnB-V9 samples were obviously better than that in MnB-V0 sample, besides, the delayed cracking resistances of MnB-V9 and MnB-V5 samples did not improve with the increase of V content, but basically remained the same. Lamellar residual austenite was found in all samples, but no hydrogen was grasped in the same area according to APT result. There was intragranular cementite in all samples, and it has grasped H in the same position. The carbides formed by V, Ti and other alloying elements were found in MnB-V5 and MnB-V9 and were considered to be an important factor in improving the anti-hydrogen delayed cracking performance of the steel.

“…I' [8][9][10][11][12] Assuming that the penetration of hydogen scales with ~]DHt where D~ is the lattice diffusion coefficient for hydrogen in nickel (-4 • 10 -1~ em 2 s-l, 28) and t is the 24 h charging period, a diffusion distance on the order of 0.06 mm is obtained. Its crosshead was driven by a stepper motor, with gearing that gave it the capacity to pull a 500 N load.…”

Constant extension rate tests (CERT) were used to evaluate the susceptibility of two cold-rolled nickel strip materials to environmentally assisted cracking (EAC) in 1.5M LiAICIJSOCI2. One strip material was made by a powder metallurgy (PM) process that started with carbonyl nickel. The other was cast and wrought (C&W). Both were 0.05 mm thick and cold-rolled to the three-quarter hard condition. The bulk impurity concentrations, grain structures, and mechanical properties of these two materials were similar. However, the C&W alloy was distinguished by a substantially higher bulk manganese content and oxygen-rich inclusions, a large fraction of which also contained sulfur. EAC of the PM alloy, manifested principally as intergranular fracture, occurred in samples that were polarized to -50, 0, and +200 mV (Li/LiCI), but not in ones that were freely corroding at +3.65 V (Li/LiCl). These results are consistent with EAC being caused by a mechanism involving zero-valent lithium, proposed by Scully et al. i In marked contrast to the PM alloy, the C&W alloy exhibited no susceptibility to Li-assisted cracking. In ancillary experiments, performed with samples that were cathodieally charged with hydrogen, only the PM alloy exhibited a high susceptibility to intergranular cracking. The present results indicate that subtle microstruetural differences may affect the reliability of Li/SOCI2 cells. Although the existing evidence is circumstantial, the results also suggest that lithium-assisted and hydrogen-assisted intergranular cracking have analogous sensitivities to grain boundary segregation of sulfur.) unless CC License in place (see abstract).
