WebIn the figure, there is the iron–iron carbide (Fe–Fe3C) 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. WebIron carbon phase diagram austenite This is also known as γFe. When we heat this solution, it converts into ferrite at a temperature above 2543°F. Austenite is usually unstable at temperatures below 727°C. This phase is non-magnetic in nature, and it changes rapidly.
