Okay I understand that carbon in Fe strengthens the metal by creating distortions within the lattice but I don't understand how temperature plays a role in determining the preferred crystal structure.

What are the reasons behind the different microstructures of steel at different temperatures? I don't understand why steel at high temperatures (austenite phase) would favor an FCC crystal structure while steel at lower temperature (ferrite) would favor a BCC crystal structure.
