Abstract

Complex study of alloys based on FeAl aluminide was leading in the fifties of the last century to the proposal of. The composition of the binary Fe-Al alloy was modified by C and Si. This alloy with excellent corrosion and heat resistant properties was used to replace the high chromium and nickel alloyed cast iron.The investigations performed recently on Fe-40 at.% Al type alloys with carbon contents 1.9 ÷ 3.8 at.% and aluminum up to 43 at.% were designed to explain in more detail the origin of the structure and mechanical properties of the mentioned material.It is the purpose of this contribution describes the effect of Al and C on the structure of iron aluminides with the composition of Pyroferal©. The appearing and morphology of carbide Al4C3 and of graphite is described in the as cast and annealed state.
