We are calling for abstracts for the Environmentally assisted cracking of high-strength materials Symposium at the 2020 MSE Congress.
Environmentally Assisted Cracking
Hydrogen-Induced Stress Cracking of Swaged Super Duplex Stainless Steel Subsea Components
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.
Is it a pit or is it a crack?
This article describes current industry practices to catalog features observed after sulfide stress cracking testing. The article also introduces a quantitative criterion to determine the maximum allowable defect size based on fracture mechanics principles.
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.
The history of NACE MR-0175, ISO 15156, and the 1% nickel limit – Timeline
This blog entry presents the development of the NACE MR-0175 in a historical perspective alongside research advancements in physical metallurgy and sulfide stress cracking.
