This investigation demonstrated 2.1 wt% tungsten drastically reduced the kinetics of tertiary phase precipitation in 25Cr super duplex stainless steels. The slow kinetics resulted in a better overall pitting corrosion resistance.
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.
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.
Submerged arc welding (SAW) – Definition
This post defines submerged arc welding process and includes a very instructive video that explains the process in detail.
Unusual Correlation between SKPFM and Corrosion of Nickel Aluminum Bronzes – Publication
In this article, we investigate the inverse correlation between Volta potentials measured by SKPFM and the observed localized corrosion morphology of NAB.
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.
