1 Introduction Hydrogen-assisted cracking (HAC) refers to a degradation mechanism of metallic materials [1-3] in a hydrogenous environment, where the migration of hydrogen atoms along the gaps between crystal lattices and grain boundaries has a corrosion effect, significantly reducing the material's resistance (e.g., strength and fracture energy) to fracture.
