Two design strategies for enhancing the thermal stability of bainitic structures

open access: yesJournal of Materials Research and Technology, 2023
In response to the growing interest of the industry in advanced high-strength steels subjected to extreme operating conditions, two novel grades BainTS and BainNiAlCu bainitic steels have been developed.

Tensile Ductility of Nanostructured Bainitic Steels: Influence of Retained Austenite Stability

open access: yesMetals, 2017
High silicon (>1.5%) steels with different compositions were isothermally transformed to bainite at 220 and 250 °C to produce what is often referred to as nanostructured bainite.

Hydrogen Susceptibility of Nanostructured Bainitic Steels [PDF]

open access: yesMetallurgical and Materials Transactions A, 2015
Abstract Nanostructured steels with an ultimate tensile strength of 1.6 GPa were produced with austenite content varying from 0 to 35 vol pct. The effect on the mechanical properties was assessed after saturating the steel with hydrogen. Elongation was reduced to 2 to 5 pct and UTS to 65 to 70 pct of prior value.

Development of advanced cementite-free bainitic steel using Ni, Al and Cu additions – Design concept and phase transformations study

open access: yesJournal of Materials Research and Technology, 2023
A novel concept, consisting of the stabilization of retained austenite with Ni, Al, and Cu additions instead of using Si as the major alloying element to prevent carbide formation, is proposed to design nanocrystalline, cementite-free bainitic steels. In

Effect of Austenitising Temperature on Mechanical Properties of Nanostructured Bainitic Steel. [PDF]

open access: yesMaterials (Basel), 2017
Nanostructured bainite was obtained in high-carbon Si-Al-rich steel by low-temperature (220–260 °C) isothermal transformation after austenitisation at different temperatures (900 °C, 1000 °C, and 1150 °C). Improved strength-ductility-toughness balance was achieved in the nanostructured bainitic steel austenitised at low temperatures (900 °C and 1000 °C)

Estimation of the Volume Percent of Normal and Nanostructured Bainite in Bainitic Steels

open access: yesMaterials 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.

Transferring Nanoscale Bainite Concept to Lower C Contents: A Perspective

open access: yesMetals, 2017
The major strengthening mechanisms in bainitic steels arise from the bainitic ferrite plate thickness rather than the length, which primarily determines the mean free slip distance.
