Webby dissolving carbon in iron. At very high temperatures, iron packs in a cubic closest packed structure that leaves just enough space to allow carbon atoms to fit in the holes between the iron atoms. Below 910ºC, iron metal packs in a body-centered cubic structure, in which the holes are too small to hold carbon atoms.
