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 ...

Microbiologically influenced corrosion in aluminium alloys and premier techniques for comprehensive identification and characterization across diverse metal types

Journal of Chemical Technology &Biotechnology, Volume 100, Issue 6, Page 1143-1158, June 2025.
Abstract Microbiologically influenced corrosion (MIC) is acknowledged as a significant type of corrosion due to its extensive impact on metal/alloy surfaces. As MIC accounts for 20% of all corrosion instances, it is a critical factor causing service failure of engineering materials such as steel and aluminium alloy.

Austenite decomposition in an X80 linepipe steel

, 2011
The final microstructure and resulting mechanical properties in the heat-affected zone (HAZ) of welded linepipes are predominantly determined by austenite decomposition during cooling after welding processes. Thus, a full understanding of continuous cooling transformation of austenite is a key step toward improving the overall performance of linepipes.

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 ...
