Very Strong, Low Temperature Bainite
On the basis of thermodynamics principles it is possible to maximise the volume fraction of bainite
Transformation without forming carbides
Low Temperature
- Higher volume fraction of bainite
- Incredibly fine microstructure (0.2 micron)
- High dislocation density (low temperature)
- High levels of carbon retained in the ferrite (0.3wt%)
Notes:
The high-carbon high-silicon bainite can also be called low temperature bainite. It differs from the classical bainite in that in transforms without forming carbides and at a low temperature (as low as 125oC) this results in an incredibly fine microstructure, high dislocation density and high levels of carbon retained in the ferrite.
