Iron-Carbon Diagram Explanation [PDF] - Mechanical E-Notes 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.

Thermodynamic description of the Fe-Cu-C system ... 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.
