Phase Diagrams of the Iron - Carbon System

Below, the phase diagram of Fe - Fe3C, as we already know it, is contrasted with the phase diagram of Fe- C
Only the latter is a "true" phase diagram showing stable equilibrium phases. The former, however, is simply more important in a practical sense because it governs what we usually call "plain carbon steels".
