TL;DR: In this article, the influence of hydrogen on the mechanical behavior of a 42CrMo4 tempered martensitic steel was investigated by means of tensile tests on both smooth and circumferentially-notched round-bar specimens precharged with gaseous hydrogen in a pressurized reactor.

TL;DR: In this paper, the fatigue crack propagation rate of quenched and tempered CrMo and CrMoV steel grades was assessed by means of tests performed on thermally precharged specimens in a hydrogen reactor at 195 bar and 450 °C during 21h.

TL;DR: In this article, the effect of displacement rate on the fracture toughness under internal hydrogen of two different structural steels grades used in energy applications was studied, and it was observed that the lower the displacement rate and the higher the steel yield strength, the stronger the reduction in fracture toughness due to the presence of internal hydrogen.

TL;DR: In this paper, the influence of hydrogen on the fracture behavior of the steel was investigated by means of fracture toughness tests using CT specimens thermally pre-charged with hydrogen gas, and scanning electron microscopy was employed to study both the resulting steel microstructures and the fracture micromechanisms that took place during the fracture tests.

TL;DR: In this paper, the authors induce a severe plastic deformation on the upper layer of the AZ31 Mg alloy in order to modulate its surface properties to slow down the kinetics of the corrosion damage.
