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.
