| 11. | This distinction arises from the diffusion rates of carbon at the temperature at which the bainite is forming.
|
| 12. | There is some controversy over the specifics of bainite's transformation mechanism; both theories are represented below.
|
| 13. | Unlike pearlite, whose formation involves the diffusion of all atoms, bainite grows by a displacive transformation mechanism.
|
| 14. | The high concentration of dislocations in the ferrite present in bainite makes this ferrite harder than it normally would be.
|
| 15. | The temperature range for transformation of austenite to bainite ( 250 550 �C ) is between those for pearlite and martensite.
|
| 16. | Bainite is a similar structure with lamellae much smaller than the wavelength of visible light and thus lacks this pearlescent appearance.
|
| 17. | Lower bainite is a needle-like structure, produced at temperatures below 350 �C, and is stronger but much more brittle.
|
| 18. | A semi-tempered middle ring of martensite and bainite, and 3 . a mild circular core of bainite, ferrite and pearlite.
|
| 19. | A semi-tempered middle ring of martensite and bainite, and 3 . a mild circular core of bainite, ferrite and pearlite.
|
| 20. | As a result of the transformation, the microconstituents, Pearlite and Bainite, form; Pearlite forms at higher temperatures and bainite at lower.
