Bainitic Ferrite Plate Thickness Evolution in Two Nanostructured Steels. [PDF]

open access: yesMaterials (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 ...

Further evidence of tetragonality in bainitic ferrite [PDF]

open access: yesMaterials Science and Technology, 2015
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 synchrotron X-ray diffraction experiments.

Experimental evidence for non-cubic bainitic ferrite [PDF]

open access: yesScripta Materialia, 2013
The first evidence is provided for the existence of a tetragonal or slightly orthorhombic unit cell of bainitic ferrite. It supports the hypothesis that the excess carbon that persists in the ferrite, which is in contact with austenite, is a consequence of an increased solubility due to the change in symmetry from the conventional cubic unit cell.

Microstructure Characteristics and Wear Performance of a Carburizing Bainitic Ferrite + Martensite Si/Al-Rich Gear Steel

open access: yesMetals, 2022
In this paper, a new low-carbon alloy gear steel is designed via Si/Al alloying. The carburizing and austempering, at a temperature slightly higher than the martensitic transformation point (Ms) of the surface and much lower than the Ms of the core, for ...

Design concept and phase transformation study of advanced bainitic-austenitic medium-Mn steel [PDF]

open access: yesScientific Reports
The isothermal heat treatment processing routes are designed for a novel 0.17 C-3.1Mn-1Si-0.55Al-0.22Mo-0.034Ti-0.073 V steel, aiming to obtain a homogeneous fine lath-type microstructure consisting of bainitic ferrite and retained austenite (RA).

Effect of Bainite to Ferrite Yield Strength Ratio on the Deformability of Mesostructures for Ferrite/Bainite Dual-Phase Steels [PDF]

open access: yesMaterials, 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.

Three-Dimensional Observation of Upper Bainite in the Initial Stage of Transformation in 0.4 wt%C TRIP Steel

open access: yesMetals, 2023
Three-dimensional microstructures of bainitic ferrites and prior austenite grains (PAGs) were observed in the initial stage of upper bainite transformation by using a serial sectioning technique and orientation analysis by electron back scattering ...

Enhanced Strength and Ductility by Introducing Nanobainitic Ferrite in Bainitic Steel Used in Sports Equipment

open access: yesMetals, 2021
The mechanical properties of carbide-free bainitic steels used in sports equipment were investigated. The nanobainitic ferrite was introduced in bainitic steel to enhance the stability of blocky retained austenite (RA).

Effect of ausforming on the bainitic transformation and microstructure in medium carbon V–N micro-alloyed steel

open access: yesJournal of Materials Research and Technology, 2023
Ausforming at 900 °C with 30% reduction in V and N micro-alloyed steel could induce VN precipitation, which has low lattice misfit (1.8%) with bainitic ferrite in a particular crystal orientation.
