Abstract Internal cavities can constitute a crack initiation site especially if filled with hydrogen at high pressure. A new refined equation of state based on recent NIST database has been introduced in order to model the equilibrium pressure. It is based on a thermodynamic definition of fugacity and uses the NIST data relating hydrogen density and pressure to define a new fugacity pressure quadratic dependence. The resulting Equation Of State (EOS) is compared to the standard Abel–Noble EOS an...

Abstract Hydrogen embrittlement induced by internal hydrogen has been identified as a critical issue for heavy components manufactured from either plain or hollow ingots made of 16MnNIMo5 through 20MnNiMo5 alloys that have the particularity to be heterogeneous at various scales. Based on available data of solubilities, diffusivities and temperature dependent phase transformations for the matrix and segregated bands, a model of hydrogen distribution in such a heterogeneous microstructure has been...

Abstract A hydrogen-charged Type-316L austenitic stainless steel represents a slight loss of tensile ductility and cup-and-cone fracture accompanied by small-sized dimple. The reduction in the dimple size is interpreted to be attributed to void sheets caused by localized slip deformations by hydrogen. This paper aims to clarify the contribution of an internal pressure to the characteristic void growth of a hydrogen-charged Type-316L stainless steel during slow strain rate tensile (SSRT) test in ...
