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. The Iron Carbon Phase Diagram. There is more to the iron-carbon phase diagram than related in the backbone. In particular, there is some nomenclature that I avoided in the main text but that is important for understanding other writings about iron and steel. So let's start with a phase diagram that contains maximal information: A 1: The upper ... The cast iron portion of the Fe-C phase diagram covers the range between 2.08 and 6.67 wt. % C. The steel portion of the metastable Fe-C phase diagram can be subdivided into three regions: hypoeutectoid (0 < wt. % C < 0.68 wt. %), eutectoid (C = 0.68 wt. %), and hypereutectoid (0.68 < wt. % C < 2.08 wt. %).

The Iron-Carbon Alloys And Fe-C Phase Diagram. The iron-carbon phase diagram and the iron-carbon systems are the most important binary systems in engineering. Steels, cast irons, and various kinds of applications are dependent on iron-carbon systems. We also explained the tin-lead phase diagram and nickel-copper phase diagrams which are also ...
The boundaries, intersecting each other, mark certain regions on the Fe3C diagram. Within each region, a different phase or two phases may exist together. At the boundary, the phase change occurs. These regions are the phase fields. They indicate the phases present for a certain composition and temperature of the alloy.
In the present study, the Fe-C phase diagram is optimized on the basis of Gustafson's results [10]. Therefore, only the parameters of the liquid phase were slightly modified, while those of the fcc and bcc phases remain the same as Gustafson's [10]. As for the metastable phase, optimized results by Göhring [17] were adopted.

A critical review of published data provides a fairly accurate knowledge of the thermodynamic properties of all of the phases of the system Fe-C that are stable or metastable at atmospheric pressure. Selected data are shown as tables and equations. A proposed phase diagram differs only slightly from others recently published but has the following features. Peritectic compositions and the α-γ ...
The study of the constitution and structure of iron and steels starts with the iron-carbon (Fe-C) phase diagram (Fig 1). Fe-C phase diagram is also used as the basis for the understanding of the heat treatment processes. Many of the basic features of Fe-C system influence the behaviour of even the most complex alloy iron and steels.
