英文摘要	The pronounced mechanical property of pearlitic steels highly correlates with the ferrite (bcc-Fe)/cementite (Fe3C) boundaries inside. Unraveling the interface structure at an atomic level is essential for interpreting the material's property. In the present study, using aberration-corrected scanning/transmission electron microscopy combined with density functional theory calculations, we reveal the atomic configuration as well as the electronic structure of the Fe/Fe3C interfaces with the Isaichev orientation in pearlite. The interface with terminating layer Fe-C-Fe in cementite has the lowest energy due to the formation of interfacial Fe-C bonds. Terrace steps which are frequently observed at the interfaces would not break the lattice match between the two phases.
