Rusting of iron is an example of corrosion. Steel is an interstitial alloy made from Carbon and iron atoms. It is significant that the sides of the face-centred cube, or the distances between neighbouring lattices in the fcc arrangement, are about 25 percent larger than in the bcc arrangement; this means that there is more space in the fcc than in the bcc structure to keep foreign (i.e., alloying) atoms in solid solution. This question seems to describe a structure like this. Free Carbon is present in Cast Iron. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix.
