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.

Effect of nickel on hydrogen permeation in ferritic/pearlitic low alloy steels – Publication.
This is the first of a series of articles on the effect of nickel on the hydrogen embrittlement resistance of low alloy steels. In this paper, we investigated how nickel in solid solution in the ferrite phase affected hydrogen permeation.
Pre-exposure embrittlement and stress corrosion cracking of magnesium alloy AZ31B in chloride solutions – Publication
In this manuscript, we investigate the influence of hydrogen on the environmentally assisted cracking of the high-strength magnesium alloy AZ31B.
Hydrogen Embrittlement of Industrial Components: Prediction, Prevention, and Models – Publication
Hydrogen embrittlement is a common, dangerous, and poorly understood cause of failure in many metal alloys. This article presents a model based on the correlation of mechanical properties to scanning electron microscopy fractography analysis of fracture surfaces in the presence of simultaneously active hydrogen embrittlement micro-mechanisms.
Hydrogen Embrittlement of Magnesium and Magnesium Alloys: A Review – Publication
In this article, we present and debate the various hydrogen embrittlement and stress corrosion cracking mechanisms of magnesium and magnesium alloys.
Are cracks born from pits?
This article describes the different forms of environmentally assisted cracking that can affect low alloy steels and corrosion resistant alloys in the oil & gas industry.
