980 MPa Grade Low-Alloy Carbide-Free Bainitic Steel Obtained by Dynamic Continuous Cooling Transformation

open access: yesCrystals, 2023
The addition of high-content alloying elements and the unbefitting process make carbide-free bainite steel difficult in industrial production. Thus, we adopted a dynamic continuous cooling process for developing the high-strength cold-rolled low-alloy ...

Application of Artificial Neural Network to the Prediction of Tensile Properties in High-Strength Low-Carbon Bainitic Steels

open access: yesMetals, 2021
An artificial neural network (ANN) model was designed to predict the tensile properties in high-strength, low-carbon bainitic steels with a focus on the fraction of constituents such as PF (polygonal ferrite), AF (acicular ferrite), GB (granular bainite),

Formation of lower bainite in a high carbon steel – an in-situ synchrotron XRD study

open access: yesJournal of Materials Research and Technology, 2022
The microstructural evolution of and simultaneous dimensional changes in high-carbon SAE 52100 bearing steel were monitored continuously during austempering for 120 min at selected temperatures in the range of 210 °C-270 °C, and also during its ...

Morphology of Widmanstätten and Bainitic Ferrites

open access: yesMaterials Transactions, JIM, 1991
The morphologies of isothermally transformed Widmanstatten and bainitic ferrites in a low carbon low alloy steel have been investigated by means of optical and electron microscopies. In the steel investigated, the Widmanstatten ferrite grains nucleated from the ferrite grain boundary allotriomorphs in the temperature range between 625 and 600 o C ...

Effect of Bainite Volume Fraction on Deformability of Mesostructures for Ferrite/Bainite Dual‐Phase Steel

open access: yesAdvances in Materials Science and Engineering, 2020
To obtain high strength and excellent deformability for ferrite/bainite dual‐phase (F/B DP) pipeline steel for gas pipelines based on strain‐based design, the volume fractions of ferrite and bainite should be considered first. In this work, abstract representative volume elements (RVE) of finite element models (FEMs) of mesostructure for F/B DP ...

Influence of Chromium Content on the Microstructure and Mechanical Properties of Thermomechanically Hot-Rolled Low-Carbon Bainitic Steels Containing Niobium

open access: yesApplied Sciences, 2020
The effect of chromium content in the range of 1 wt.%−4 wt.% on the microstructure and mechanical properties of controlled-rolled and direct-quenched 12 mm thick low-carbon (0.04 wt.%) steel plates containing 0.06 wt.% Nb has been studied. In these

C-Curves for Lengthening of Widmanstätten and Bainitic Ferrite [PDF]

open access: yesMetallurgical and Materials Transactions A, 2017
Abstract Widmanstätten ferrite and bainitic ferrite are both acicular and their lengthening rate in binary Fe-C alloys and low-alloyed steels under isothermal conditions is studied by searching the literature and through new measurements. As a function of temperature, the lengthening rate can be represented by a common curve for both kinds of
