ISIJ International, 1995 There are three controversies regarding the formation of bainite. One concerns the mechanism by which lattice atoms leave the fcc lattice and form the new bcc lattice. The second one concerns the question of local equilibrium and the role of carbon diffusion. The third one concerns the question whether each little region transforms in two steps or not.

Estimation of the Volume Percent of Normal and Nanostructured Bainite in Bainitic Steels
Materials Today: Proceedings, 2015 Abstract Estimation of the volume percent of bainite has been conducted using a powerful computational technique known as neural network. The model is proposed for ordinary bainitic steel in addition to the more recent class of super bainite steel which are attractive for many applications.

Evaluation of displacive models for bainite transformation kinetics in steels
, 2013 Several kinetic models for bainite transformation have been widely applied in industry and research. The majority of these models, that do not consider the effect of cementite precipitation during bainite transformation, were validated in high silicon ...

Slow Bainite: an Opportunity to Determine the Carbon Content of the Bainitic Ferrite during Growth
Solid State Phenomena, 2011 The amount of carbon in solid solution in bainitic ferrite at the early stage of transformation has been directly determined by atom probe tomography at 200 °C, taking advantage of the extremely slow transformation kinetics of a novel nanocrystalline steel.

In situ observation of bainite growth during isothermal holding
, 2006 The mechanism of bainite growth has been investigated using in situ transmission electron microscopy observations. It was found that, in a number of alloys studied, a bainitic embryo is made of basic transformation units.

Carbon content of bainite ferrite in 40CrMnSiMoV steel
, 2009 A refined method for analysing X-ray diffraction spectrum was used to determine the carbon content of bainite ferrite in 40CrMnSiMoV steel. The supersaturated carbon concentration linearly decreases with increase of isothermal holding time at 310 °C due ...
