Shopping. Tap to The Iron-Iron Carbide (Fe-Fe3C) Phase Diagram Development of Microstructure in Iron-Carbon Alloys 9.46 This problem asks that we compute the mass fractions of α ferrite and cementite in pearlite. The lever-rule expression for ferrite is Wα = CFe 3C − C0 CFe 3C − Cα and, since CFe 3C = 6.70 wt% C, C0 = 0.76 wt% C, and Cα = 0.022 wt% C There are three three-phase equilibria in the iron-carbon diagram shown: At 1495°C: δ-ferrite + Liquid=γ-iron (austenite), a peritectic reaction, defined on cooling as a solid phase combining with liquid phase to form a single solid phase.
