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.

Corrosion behavior of buried pipeline in presence of AC stray current in a controlled environment (Paper no. C2015-5588)

May 29, 2015 by Mariano Iannuzzi

This blog entry provides the link to download our final NACE CORROSION 2015 publication on corrosion of carbon steel in the presence of alternate currents (AC). Elmira Ghanbari presents a model, based on fundamental corrosion principles, which estimates the effect of an applied AC interference on Faradaic processes leading to corrosion.
