Physical Metallurgy

The Role of Tungsten on the Phase Transformation Kinetics and its Correlation with the Localized Corrosion Resistance of 25Cr Super Duplex Stainless Steels

May 29, 2020 by Mariano Iannuzzi

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

August 1, 2019 by Mariano Iannuzzi

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.

April 26, 2018 by Mariano Iannuzzi

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.

Unusual Correlation between SKPFM and Corrosion of Nickel Aluminum Bronzes – Publication

September 11, 2017 by Mariano Iannuzzi

In this article, we investigate the inverse correlation between Volta potentials measured by SKPFM and the observed localized corrosion morphology of NAB.

Hydrogen Embrittlement of Industrial Components: Prediction, Prevention, and Models – Publication

March 21, 2017 by Milos Djukic

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.
