1. Diffusional transformations like austenite transforming to a cementite and free energy. 2. After cementite is formed, the integrity of the disc is compromised. 3. No large inclusions of cementite will form at the boundaries in hypoeuctoid steel. 4. This type of diffusion, called ferrite and cementite , becoming soft pearlite. 5. When given more time, stable microconstituents can form : ferrite and cementite . 6. When slowly cooling a hypereutectoid steel, the cementite will begin to crystallize first. 7. Further heating reduces the martensite even more, transforming the unstable carbides into stable cementite . 8. A fine non-lamellar structure, bainite commonly consists of cementite and dislocation-rich ferrite. 9. Since cementite is much harder than pearlite, the alloy has greater hardenability at a cost in the ductility. 10. When austenite is cooled extremely slow, it will form large ferrite crystals filled with spherical inclusions of cementite .
