... Fe-Fe 3 C or Fe-Gr system, cast iron can be defined as an iron-carbon alloy with more than 2% C. However, because silicon and other alloying elements considerably change the maximum solubility of carbon in austenite (γ) and in the eutectic, a more general definition of cast iron is that it is an iron...

... elements may considerably change the maximum solubility of carbon in austenite. Therefore, in exceptional cases, alloys with less than 2% C can solidify with a eutectic structure and still belong to the family of cast iron. The formation of stable or metastable eutectic is a function of many factors...

When the chromium content of cast iron is greater than ∼10%, eutectic carbides of the M 7 C 3 type are formed, rather than the M 3 C type that predominates at lower chromium contents. More significantly, however, the higher chromium content causes a change...
