Bainitic Ferrite Plate Thickness Evolution in Two Nanostructured Steels. [PDF]
Materials (Basel), 2021 Bainitic ferrite plate thickness evolution during isothermal transformation was followed at the same holding temperatures in two nanostructured steels containing (in wt.%) 1C-2Si and 0.4C-3Si. A dynamic picture of how the bainitic transformation evolves was obtained from the characterization of the microstructure present at room temperature after full ...

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.

Partial austenitisation and TBF steel composed of ferrite, bainitic ferrite, and austenite
Materials Science and Technology, 2023 A TRIP-aided bainitic-ferritic (TBF) steel with a chemical composition of Fe–0.19C–1.7Mn–1.09Si–0.51Al–0.05Nb (wt-%) was partially austenitised from a hot-rolled martensitic initial microstructure. After the hot rolling, the martensitic specimens were reheated to different intercritical temperatures and then austempered at 350°C.

Carbon supersaturation of ferrite in a nanocrystalline bainitic steel [PDF]
Acta Materialia, 2010 The extremely slow transformation kinetics of a nanocrystalline bainitic steel allows the carbon content of the bainitic ferrite away from any carbon-enriched regions such as dislocations and boundaries to be determined by atom probe tomography as the bainite transformation progresses at 200 C. A high level of carbon, well above that expected from para-

In situ observation of bainitic transformation behavior in medium carbon bainitic steel
Journal of Materials Research and Technology, 2022 The bainitic transformation behavior of samples with different scales was observed with dilatometer (DIL), high-temperature laser scanning confocal microscope (LCSM), and environmental transmission electron microscope (ETEM).

Do bainitic and Widmanstätten ferrite grow with different mechanisms?
Scripta Materialia, 2010 Caballero et al. recently presented new evidence for different growth mechanisms of Widmanstatten and bainitic ferrite. Their argument was based on Zener's hypothesis of diffusionless growth of bainitic ferrite. It is now demonstrated that Bhadeshia's model, based on Zener's hypothesis, predicts that some of the new measurements, claimed to fall above ...

New Insights into Carbon Distribution in Bainitic Ferrite*
HTM Journal of Heat Treatment and Materials, 2018 Abstract A number of studies on bainite transformation at low temperature have revealed that bainitic ferrite formed super-saturated in carbon. The most sensible explanation to this is the increased solubility of a tetragonal ferrite lattice, by virtue of synchrotron radiation and X-ray diffraction results, as well as ab-initio ...

Effect of Dislocation Density on Deformation Behavior of Super Strong Bainitic Steel
Journal of Advanced Materials in Engineering, 2017 Presence of nanoscale bainitic ferrites and high carbon retained austenites that are stable at ambient temperature within the microstructures of super strong bainitic steels makes it possible to achieve exceptional strengths and ductility properties in ...

Effect of Bainite to Ferrite Yield Strength Ratio on the Deformability of Mesostructures for Ferrite/Bainite Dual-Phase Steels [PDF]
Materials, 2021 The strength and plasticity balance of F/B dual-phase X80 pipeline steels strongly depends on deformation compatibility between the soft phase of ferrite and the hard phase of bainite; thus, the tensile strength of ferrite and bainite, as non-negligible factors affecting the deformation compatibility, should be considered first.
