The Iron Carbon Phase Diagram

The Iron-Carbon phase diagram illustrates how iron and carbon interact at different temperatures and compositions, showing the formation of various steels and cast irons. It reveals the temperatures at which iron changes structure (like from austenite to ferrite or cementite) and highlights stable phases depending on carbon content. This diagram helps engineers understand material properties, such as hardness and strength, guiding the production of different types of steel suited for specific applications. Essentially, it maps the relationship between temperature, carbon amount, and the resulting microstructure of iron-based alloys.
