Based on the carbon percentage found in the diagram, alloys are categorized as: < 0.76% Carbon. Hyper-eutectoid Steel: 0.76% to 2.14% Carbon.
A solid solution of carbon in Body-Centered Cubic (BCC) iron. It is soft, ductile, and magnetic at low temperatures.
Whether you are preparing for an exam or working in a foundry, having a reliable on your device is essential for quick reference. What is the Iron-Carbon Equilibrium Diagram?
Heating to austenite and cooling in still air to refine grain structure.
It illustrates the transformations that occur during heating and cooling, which ultimately determine the mechanical properties—like hardness, ductility, and tensile strength—of the metal. Key Phases in the Diagram
A solid solution of carbon in Face-Centered Cubic (FCC) iron. It is non-magnetic and only exists at high temperatures (above 727°C) in plain carbon steels.
A lamellar (layered) mixture of ferrite and cementite that forms during slow cooling.
