The Iron-Carbon Phase Diagram. In their simplest form, steels are alloys of Iron (Fe) and Carbon (C). The study of the constitution and structure of iron and steel start with the iron-carbon phase diagram. It is also the basis understanding of the heat treatment of steels.The Iron Carbon diagram is shown in Fig. 1.n their simplest form, steels are alloys of Iron (Fe) and Carbon (C).
