“…Nevertheless, a hydrogen induced ductility loss has unfortunately been revealed in duplex and austenitic steels. [21][22][23][24] Luo et al [25] considered 2205 duplex stainless steel with a thickness of 0.5 mm. They charged the material electrochemically in a 0.5 M H 2 SO 4 electrolyte containing 0.25 g L À1 As 2 O 3 solution for ten days at À1500 mV SCE .…”

This study considers the interaction between duplex stainless steel type 2205 and electrochemically charged hydrogen. Duplex stainless steels combine the mechanical properties of ferrite with the corrosion resistance of austenite and are widely used in many industrial applications. However, they are susceptible to hydrogen embrittlement. In this work, the steel microstructure is first characterized by scanning and transmission electron microscopy, X‐ray diffraction, and electron backscatter diffraction. Subsequently, melt extraction is done to determine the amount of hydrogen charged into the material, while in situ hydrogen charged tensile tests are combined with a fractography analysis to evaluate the effect of hydrogen on the mechanical behavior. The material displays a rather significant ductility loss of about 26% as a result of the applied hydrogen charging. Melt extraction identifies the increased hydrogen content in the steel microstructure (up to 50 wppm). Moreover, the hydrogen embrittled regions correspond well to the hydrogen diffusion penetration depth from the edges onwards. These cleavage brittle areas are observed up to the theoretical hydrogen diffusion distance, demonstrating the hydrogen embrittlement effect.

“…The hydrogen embrittlement susceptibility of austenitic steels has therefore been the focus of considerable research interest in the hydrogen-energy-related research field. [1][2][3][4] High Mn austenitic alloys containing ε-martensite exhibit good potential in the development of new high strength materials with low hydrogen embrittlement susceptibility. The addition of ε-martensite is considered to improve hydrogen embrittlement resistance because of the following reasons.…”

“…In addition, some interstitial atoms such as nitrogen and carbon promote deformation localisation in austenitic steels. 11,12) In contrast, it was reported 13,14) that introducing dislocations into 316L steels without any martensitic transformation increased the hydrogen trapping, but led to a slight ductility loss due to hydrogen itself.…”

Hydrogen Embrittlement of Ultrafine-grained Austenitic Stainless Steels Processed by High-pressure Torsion at Moderate Temperature

et al. 2016

The effect of hydrogen on the plasticity of ultrafine-grained austenite was studied on type 304, 316L, and 310S stainless steels processed by high-pressure torsion at moderate temperature. Like austenitic steels with ordinary grain sizes, the hydrogen-induced ductility loss for the ultrafine grains became more pronounced with decreasing stability of the austenitic phase. For all the steels, the uniform elongation was limited by strengthening due to the ultra grain refinement; the ultrafine-grained 310S stable austenitic steel further exhibited a small local elongation due to a lack of martensitic transformation. The ductility loss due to hydrogenation for 316L steel with an intermediate austenite stability was retained to a moderate level. The ultrafine-grained 304 metastable austenitic steel exhibited a serious ductility loss induced by hydrogen showing localised shear deformation. This suggests that the dynamic martensite transformation plays a crucial role in the hydrogen embrittlement of ultrafine-grained metastable austenitic steel.
