Webb10 nov. 2016 · The HISC phenomenon is driven by dislocation movement due to applied stress, but DNV-RP-F112 provides limits in terms of both stress and strain. A method is presented to determine strains caused exclusively by stress and not by thermal expansion or the Poisson effect. Webb4 apr. 2024 · HISC is the Achilles’ heel of duplex and super duplex stainless steels. In this investigation, we demonstrate the detrimental effects of both cold work (swaging) and anisotropic microstructures on HISC resistance. We believe the findings challenge the validity of the present form of DNV-GL RP F112 as a method to reduce HISC risks.
