What is Phase diagram: Definition and 54 Discussions

For the use of this term in mathematics and physics, see phase portrait and phase space.
A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, volume, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium.

    Exploring the Fe-C Phase Diagram: 0.2% C Content

    Fe-C phase diagram Can someone explain to me what happens in the Fe-C phase diagram during cooling from melt to room temperature when the content of C is 0,2%? All those lines in the diagram confuse me a bit... What I don't get is how I can say anything about what happens in room temperature...
