Of less interest, except for highly alloyed steels, is the delta-ferrite at the highest temperatures. The vast majority of steels rely on just two allotropes of iron: (1) alpha-iron, which is body-centered cubic (BCC) ferrite, and (2) gamma-iron, which is face-centered cubic (FCC) austenite. Cementiteor iron carbide is very hard, brittle intermetallic compound of iron & carbon, as Fe3C, contains 6.67 % C. It is the hardest structure that appears on the diagram, exact melting point unknown. Its crystal structure is orthorhombic. It is has low tensile strength (approx. 5,000 psi), but high compressive strength. 2015-05-25 · The Fe-Fe 3 C binary phase diagram under high magnetic fields up to 21 T was investigated by a differential thermal analysis.
