Unravelling the effect of F phase on hydrogen-assisted intergranular cracking in nickel-based Alloy 725: Experimental and DFT study

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 density functional theory (DFT) calculations. The results show grain boundary precipitate F phase promotes intergranul...
