This single layer is the precursor of the body centered cubic (BCC) unit cell. The lattice points are in the same general form as the simple cubic (SC) unit cell, with the exception that the atoms are ...

The interstitial alloy between carbon and iron has a complex phase diagram. A compound, Fe 3 C with the fixed composition Fe-6.7 wt % C bounds one end of this diagram and pure iron the other end. Pure ...

Iron goes from a face-centered cubic (FCC) structure—the gamma phase, or austenite—at high temperatures to a body-centered cubic (BCC) structure—alpha phase, or ferrite—at a lower ...
