SUMMARY
Carbon preferentially occupies octahedral sites in steel made with ferrite (Fe with BCC structure). Within these octahedral sites, there are two types: face-centered and edge-centered. The discussion indicates that while carbon generally prefers octahedral sites, it may favor edge-centered sites due to their deformations. A reference from IITK's presentation on voids in crystals supports this conclusion, although it does not differentiate between the two types of octahedral sites.
