WebIron-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. WebTTT diagrams for (a) eutectoid, (b) hypoeutectoid, and (c) hypereutectoid steels. (b) and (c) show ... Cementite is a metastable phase, and there exists a true equilibrium between iron and graphite. In cast irons (2–4 wt% C) graphite occurs extensively. Equilibrium phase in steel (0.03–1.5 wt% C) is much more difficult to obtain. ray huff auburn al https://veritasevangelicalseminary.com
