Corrosion is a costly and ubiquitous challenge facing many industries, with trillions of dollars spent annually to repair and remediate corroded materials across sectors ranging from infrastructure and transportation to production and manufacturing. Prior to the current work, much of the research investigations into steel corrosion have been performed ex-situ. For steels containing a cementite phase, such studies show that corrosion-induced cracking occurs along cementite/ferrite boundaries, although inherent limitations to ex-situ observations still limit our understanding of the initial onset and development of the corrosion process. Here, we present our investigation of the corrosion cracking process in 1018 carbon steel using in-situ TEM liquid flow-cell corrosion techniques to directly investigate this failure phenomenon at the nanoscale.
