“…and TWIP advanced high-strength steels, especially the ductility [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Previous research [29], under conditions of electrolytic hydrogen charging using the linearly increasing stress test (LIST), showed that all the tested DP, Q&P and TWIP advanced high-strength steels exhibited HE susceptibility, manifested by (a) a reduced yield stress, and (b) reduced ductility attributed to a change of fracture mode at the ultimate tensile strength. There was no sub-critical crack growth at stresses below the ultimate tensile strength…”

The hydrogen influence was evaluated (A) for laboratory conditions with hydrogen concentrations larger than in service, and (B) at substantial loading rates to simulate a crash. Hydrogen in the studied laboratory conditions caused minimal influence for 980DP and 1200DP, and some influence for 980DP-650YS, 980DP-700YS, 980QP and 950TW. Simulated crash situations caused some influence for 980DP, 980QP and 950TW; their properties quickly reverted after the end of hydrogen charging. Two new mechanisms are proposed: (i) hydrogen enhanced macroscopic plasticity (HEMP) decreasing the yield stress, and (ii) hydrogen assisted micro-fracture (HAM) decreasing ductility at fracture at the ultimate tensile strength.

“…The high carbon steel (HCS) has been dominantly used for many mining and pharmaceutical applications due to its high reliability in strength, hardness, and abrasion resistance [1][2][3]. However, with a mediocre level of corrosion resistance, this grade of metal alloy is susceptible to corrosion, which can increase the cost of maintenance [3].…”

Series of super-hard ceramic layers have been successfully developed on high carbon steels, with a significant improvement of corrosion resistance and hardness, without changing the original properties, which were derived from mixtures of slag (electric arc furnace), waste glass (bottles), and automotive shredder residue (ASR) plastics (polypropylene) via the single step surface modification technique. Microstructural analysis by laser scanning confocal microscopy (LSCM), crystallography analysis by X-ray diffraction (XRD), micro-level chemical analysis by scanning electron microscopy and energy dispersive spectroscopy (SEM and EDS), and depth profile surface analysis with three-dimensional chemical mapping by time-of-flight secondary ion mass spectrometry (TOF-SIMS), followed by electrochemical corrosion test by the Tafel method and hardness test—Vickers hardness measurement. Three areas have been classified, modified surface, interface, and main substrate areas as the synthesis of ceramic layers into surface of the steels that thermodynamically formed during the heat treatment process. Chemical composition analyses have revealed that generated layers consisting of chromium (Cr)- and magnesium (Mg)-based compound have shown an improved corrosion resistance to 52% and hardness to 70% without modifying the initial volume fraction of constituent phases–martensite and retained austenite. These findings have substantially highlighted to the potential use of waste-integrated inputs as raw materials for production in cost-effective way, concurrently decreasing the demand on new resource for coating, alleviating the disadvantageous impact to the environment from waste disposal in landfills.

“…There is also the interaction of hydrogen with the new steels (the advanced high strength steels (AHSS)) being used to make lighter, more crash worthy cars that produce less CO 2 because they are more fuel‐efficient. Our prior research has dealt with the influence of hydrogen on the mechanical strength of medium strength steels and AHSS . The present work extends this research into the area of fatigue.…”

The influence of hydrogen on low cycle fatigue (LCF) of 3.5NiCrMoV steel electrochemically hydrogen charged in the acidified pH 2 0.1 M Na2SO4 solution is studied. In the presence of hydrogen, the fatigue life decreases significantly by ≈70 to ≈80% by: (i) the crack initiation period is decreased; and (ii) the crack growth rate is accelerated. SEM observation indicates that in the presence of hydrogen, the fracture surface shows flat transgranular fracture with vague striations and some intergranular fracture at lower stresses. The fatigue crack growth rate increases with increasing cyclic stress amplitude and with hydrogen fugacity. Once the fatigue crack reaches a critical length, the specimen becomes mechanical unstable and fracture due to ductile overload occurs. The hydrogen contribution to the final fracture process is not significant.
