This sceencast is focused on addressing issues students have with Iron-Iron Carbide (Steel) E... 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. In heat treatment processes of steel the very important role plays the Fe-Fe3C phase equilibrium diagram. It enables the selection of the temperature of ...

Fe-Fe 3 C T-T-T Diagram, Adapted from Callister pg. 295, Fig. 10.6. The time-temperature transformation curves correspond to the start and finish of transformations which extend into the range of temperatures where austenite transforms to pearlite. Above 550 C, austenite transforms completely to pearlite.

phase diagram has not been well established---in the temperature, composition, and pressure ranges not related directly to iron and steel making. In the present evaluation, the assessed stable Fe-C (graphite) and metastable Fe-Fe3C (cementite) equilibrium phase diagrams for 0 to 25 at.% C are based on thermodynamic calculations reported The Iron ‐ Iron Carbide (Fe‐Fe3C) Phase Diagram Reactions Phases Present Peritectic L + δ = γ Lat T=1493oC and 0.18wt%C δ ferrite delta Eutectic L = γ + Fe3C Bcc structure at T=1147oC and 4.3wt%C Paramagnetic Eutectoid γ = α + Fe3C γ austeniteat T=727oC and 0.77wt%C Fcc structure Non‐magnetic ductileMax. solubility of C α ferrite Fe3C cementitein ferrite=0.022% Bcc structure ...
