Classification of pitting corrosion damage in process facilities using supervised machine learning

The Canadian Journal of Chemical Engineering, Volume 103, Issue 1, Page 153-169, January 2025.
Abstract Corrosion is widely known to be a major cause of the failures in process facilities. Prediction of corrosion damage is therefore essential for industries to manage the availability of their assets. This research aims to investigate the application of supervised machine learning methods for the classification of pitting corrosion damage ...

Hydrogen embrittlement susceptibility of a high strength steel X80 [PDF]

Materials Science and Engineering: A, 2010
The present paper deals with hydrogen embrittlement (HE) susceptibility of a high strength steel grade (X80). The respective implication of different hydrogen populations, i.e. adsorbed, dissolved in interstitial sites, trapped on dislocations and/or microstructural elements on the associated embrittlement mechanisms has been addressed through ...
