Hydrogen is considered a clean and efficient energy carrier crucial for shaping the net-zero
future. Large-scale production, transportation, storage, and use of green hydrogen are …

We conduct in situ tensile straining experiments to investigate the role of hydrogen and slip
in crack initiation in nickel-based alloy 725. Our experiments reveal no tendency for …

To overcome the Hydrogen embrittlement (HE) susceptibility of the standard Alloy 725 (Mod
A), two alloys with minor alloying modifications with B (Mod B) and B+ Cu (Mod C) were …

The effect of hydrogen on the surface morphology and nanomechanical properties of Ni-
based Alloy 725 under solution-annealed (SA) and precipitation-hardened (API) conditions …

Recently, several hydrogen-assisted failures have been reported on different nickel alloys
used in the subsea oil and gas industries. It is thus essential to correlate hydrogen uptake …

The high cracking susceptibility is the major obstacle to the wide application of high γ′-
phase nickel-based superalloys in additive manufacturing. It is especially important to …

From the two possible intergranular phases in nickel alloy 725 (UNS N07725, Inconel 725),
ie, M 23 C 6 and the σ-related F phase, the abundant formation of F phase was found to …

In situ electrochemical microcantilever bending tests were conducted in this study to
investigate the role of grain boundaries (GBs) in hydrogen embrittlement (HE) of Alloy 725 …

Precipitation at grain boundaries is typically not regarded as an efficient method for
strengthening materials since it can induce grain boundary embrittlement, which …

The grain-based model (GBM) stands as a renowned model for polycrystalline simulations
in computational mechanics. Despite its popularity, there remains a critical need for a more …
