Alpha-iron has a Body
Centered Cubic crystal structure and carbon can form an interstitial solid
solution in the matrix. It is relatively ductile.
Iron carbide is
a compound Fe3 C, and is a brittle ceramic-like material. The
presence of these two phases in Pearlite makes this material less ductile,
and it has a higher work hardening rate than the single phase Austenite. |
