Fe-C phase diagram

The Fe-C phase diagram illustrates how iron (Fe) and carbon (C) behave at different temperatures and carbon concentrations. It shows the various phases of steel and cast iron, including solid solutions and compounds like cementite. As carbon content increases, the properties of iron change, affecting hardness, strength, and ductility. Key regions include ferrite (pure iron), austenite (high-temperature phase), and cementite (iron carbide). Understanding this diagram helps in producing materials with desired characteristics for construction, manufacturing, and engineering applications.
