Improving strength and ductility via ausforming combined with austempering through deformation-induced bainite refinement

Journal of Materials Research and Technology
The refinement of bainitic ferrite laths is one of the most critical ways to improve the combination of strength and ductility. However, low-temperature bainitic transformations in the microstructural evolution of carbide-free bainite in high-carbon ...

The Acceleration of Phase Transformation and Strength–Toughness Match by Cerium Addition for Low‐Temperature Bainite

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The engineering application of traditional nano‐bainite steel, also known as low‐temperature bainite steel, has been restricted due to its relatively low toughness and the prolonged isothermal transformation time during manufacturing processes.

Mechanism of Inverse Bainitic Transformation in High Carbon Steels

, 2019
The formation of bainite is the most studied and the most debated phase transformation in steels, with research spanning almost a century. With two theories of transformation, the transformation mechanism of bainite is still a disputed subject among ...

BAINITE : MOBILITY OF THE TRANSFORMATION INTERFACE

Le Journal de Physique Colloques, 1982
Experimental evidence is provided to show that the interface responsible for the austenite to bainite transformation exhibits the essential characteristics of a glissile, semi-coherent interface. The experiments involve a comparison between the rate of formation of bainite, and the mobility of an interface whose motion does not lead to the formation of

A coupled phase field/diffusional/mechanical framework for simulation of upper and lower bainitic transformation

International Journal of Solids and Structures, 2019
The microstructure bainite in steels consists of three phases, namely bainitic ferrite, austenite and carbide. Two different arrangements of these phases can be observed denoted as upper and lower bainite which develop at different temperatures. For both

Regulating the Boron Content to Suppress Stress‐Relief Cracking in the Coarse‐Grained Heat‐Affected Zone of 7CrMoVTiB10.10 Heat‐Resistant Alloy

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT This study demonstrates a new strategy for modifying the boron content to address stress‐relief cracking (SRC) in the 7CrMoVTiB10.10 alloy. First, coarse‐grained heat‐affected zone (CGHAZ) specimens with different boron contents were prepared via simulated welding thermal cycles.

A Comparative Study on the Dynamic Tensile Behavior of Nanostructured Bainitic and Quenched-Tempered Martensitic Steels

Metals, 2018
In order to assess the dynamic tensile behavior of a newly developed three-step low-temperature-transformed bainitic microstructure, and a conventional one-step isothermal bainitic microstructure, and a quenched and tempered martensitic microstructure, a

Cyclic Plastic Material Behavior of Novel Austenitic (C + N) Steel Additively Manufactured by PBF‐LB/M

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 4, Page 1313-1326, April 2026.
ABSTRACT The newly introduced high manganese high strength (C + N) steel Printdur HSA was developed for the additive manufacturing process PBF‐LB/M. It consists of a fully austenitic grain structure. This study aims to evaluate the cyclic plastic material behavior of this (C + N) steel.
