In an interstitial solid solution diffusion can take place with relative ease since the solute atom being small such as carbon atoms occupying the interspacing distance of the iron atoms. Thus, in case of cast iron 4-6%C, brittle fracture will be expected because of the followings: * Carbon atoms of non- metal themselves possess no ductility. Loss of ductility as the interatomic O distance has been occupied by carbon atoms. O All. The increase of hardness as carbon content increases. The carbon atoms diffuse between O iron atoms ,thus reduce the interatomic attraction.
