| 1. | The microstructures of martensite and bainite at first seem quite similar.
|
| 2. | Thus, martensite can be thermally induced or stress induced.
|
| 3. | Bainite is an intermediate of pearlite and martensite in terms of hardness.
|
| 4. | In this figure, ? ( T ) represents the martensite fraction.
|
| 5. | The transition from martensite to austenite produces force and deformation.
|
| 6. | There is no thermal activation energy for the transformation from austenite to martensite.
|
| 7. | However, the martensite transformation is time-independent.
|
| 8. | A very rapid quench is essential to create martensite.
|
| 9. | Untempered martensite is low in toughness and therefore brittle.
|
| 10. | The strength of the martensite is reduced as the amount of retained austenite grows.
