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.
Materials and corrosion trends in offshore and subsea oil and gas production – Publication
In this article, we discuss materials and corrosion research topics that could have a transformative effect on the business. In particular, we discuss how scientists and engineers could push the boundaries of existing technologies, learning from the experience gained by other industries such as the nuclear, aerospace, and defense sectors.
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.
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.
Pre-exposure embrittlement and stress corrosion cracking of magnesium alloys in chloride solutions — Presentation
Do magnesium alloys suffer environmentally assisted cracking?
In this work, presented at CORROSION 2014, we investigated the hydrogen embrittlement and stress corrosion cracking of magnesium alloy AZ31B in chloride solutions.
