Further evidence of tetragonality in bainitic ferrite [PDF]
, 2014 There is growing evidence that bainitic ferrite which retains a substantial amount of carbon in solid solution does not have cubic symmetry. We provide additional data on a different nanostructured bainitic steel to support this evidence, based on ...

Widening of Laths in Bainite [PDF]
Metallurgical and Materials Transactions A, 2017 Abstract Units of bainite in Fe-C alloys from the upper temperature range inherit their shape from Widmanstätten plates of ferrite, which are lathlike. The thickness increases by long-range diffusion of carbon and the length by short-range diffusion of carbon from the advancing edge of the tip.

Bainite transformation under the effect of large stress in a carbide-free bainite steel
Journal of Materials Research and Technology, 2023 The effects of large stress on bainite transformation and microstructure were investigated by dilatometry, SEM and EBSD. The results show that the effect of large stress on bainite transformation includes two parts: mechanical driving force and prior ...
