The iron-carbon diagram provides a valuable foundation on which to build knowledge of both plain carbon and alloy steels in their immense variety. Fig. 1. The iron-carbon diagram. It should first be pointed out that the normal equilibrium diagram really represents the metastable equilibrium between iron and iron carbide (cementite). The iron-iron carbide (Fe-Fe 3 C) phase diagram. The percentage of carbon present and the temperature define the phase of the iron carbon alloy and therefore its physical characteristics and mechanical properties. The percentage of carbon determines the type of the ferrous alloy: iron, steel or cast iron.

According to the Mg–Ag binary phase diagram, the maximum equilibrium solid solubility of Ag in Mg is ∼15 wt% at the eutectic temperature of 472 °C, and it falls to approximately 2 wt% at room temperature, and the intermetallic phase at the Mg-rich side of the phase diagram is Mg 3 Ag (space group P6 3 /mmc, a = 0.488 nm, c = 0.779 nm). Part of the iron-carbon thermal equilibrium diagram A diagram showing the relationship between carbon content, microstructure and Mechanical properties of plain carbon steels in the normalized ... Iron-Carbon Phase Diagram with Detailed Explanation: If the percentage of the carbon is in the range of 0 to 2.11 % then it is called Steel and if the percentage of carbon is in the range of 2.11 to 6.67% then it is called Cast iron. As the carbon content increases, it produces more Iron-Carbide volume and that phase will exhibit high hardness. Iron carbide equilibrium diagram shows us metastable conditions, one can achieve equilibrium changes under slow heating and cooling. Importance of Iron Carbon Equilibrium Diagram According to the requirements of different applications, we can develop new alloys by handing them at different temperatures and changing the compositions of carbon in it.

The iron -carbon phase diagram in Fig 2 actually shows two diagrams namely (i) the stable iron-graphite diagram (red lines), (ii) and the metastable Fe-Fe3C diagram. Cementite is metastable, and the true equilibrium is to be between iron and graphite (C).

Iron Carbon diagram

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide converts iron oxides to elemental iron. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide.

Iron-Cementite diagram is not a true equilibrium diagram, since equilibrium means no change of phase with time, however long it may be. Graphite is more stable form of carbon. Cementite is a metastable phase, which decomposes to graphite if given long periods of time. Graphitisation, however, rarely occurs in steels and may take years to form.
