based Alloy 725 under solution-annealed (SA) and precipitation-hardened (API) conditions …

The effect of the scarcely reported F phase on hydrogen-assisted cracking in nickel-based
Alloy 725 was thoroughly studied by combining tensile tests, advanced characterization, and …

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 …

From the two possible intergranular phases in nickel alloy 725 (UNS N07725, Inconel 725),
