Figure 1: The leftmost diagram illustrates a theoretical cubic structure. Two cubic steel structures are body-centered cubic (BCC), also known as ferrite (second from left), and face-centered cubic (FCC), which is austenite (third from left). The face-centered tetragonal (FCT) structure, far right, is known as martensite. The FCT structure is about 14 percent larger than the FCC structure.

It involves excursions above and below room temperature.
