While the behavior of steel has been studied extensively for decades, there are still open questions regarding the microstructures it forms. In this talk, we examine the validity of atomistics in gaining further insight into the structure of pearlite. Multiple interatomic potentials for the iron-carbon system were examined and their ability to model the behavior of cementite and ferrite was tested. As there are many proposed orientation relationships within pearlite from experiment, none of which there is consistent agreement upon, we have provided an atomistic voice to the discussion. Models were constructed for the commonly proposed orientation relationships between cementite and ferrite, including the Isaichev, the Bagaryatskii and the Pitsch-Petch, and the energetics determined. For each orientation relationship, the interfacial energy and structure of the interface determined by the various potentials showed many similarities, lending itself to the validity of atomistics in the study of steel.
