Electronic origin of the anomalous segregation behavior of Cr in Fe-rich Fe-Cr alloys
Maximilien Levesque, Michèle Gupta, Raju P. Gupta
The energy of segregation of Cr from the bulk to the topmost surface layer in dilute Fe-Cr alloys is endothermic but small. On the other hand, the segregation energy from the bulk…
Effect of surface hydrogen on the anomalous surface segregation behavior of Cr in Fe-rich Fe-Cr alloys
Michèle Gupta, Raju P. Gupta, Maximilien Levesque
The segregation behavior of Cr in dilute Fe-Cr alloys is known to be anomalous since the main barrier for surface segregation of Cr in these alloys arises not from the topmost surf…
Simple concentration-dependent pair interaction model for large-scale simulations of Fe-Cr alloys
Maximilien Levesque, Enrique Martínez, Chu-Chun Fu +2
This work is motivated by the need for large-scale simulations to extract physical information on the iron-chromium system that is a binary model alloy for ferritic steels used or…
Anomalous Surface Segregation Profiles in Ferritic FeCr Stainless Steel
Maximilien Levesque
The iron-chromium alloy and its derivatives are widely used for their remarkable resistance to corrosion, which only occurs in a narrow concentration range around 9 to 13 atomic pe…
