The Nature of Bainite.

ISIJ International, 1995
There are three controversies regarding the formation of bainite. One concerns the mechanism by which lattice atoms leave the fcc lattice and form the new bcc lattice. The second one concerns the question of local equilibrium and the role of carbon diffusion. The third one concerns the question whether each little region transforms in two steps or not.

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.

Enhancing strength without sacrificing ductility in medium-carbon multiphase bainitic steel through increased intercritical annealing temperatures

Journal of Materials Research and Technology
In bainitic steels, enhancing strength often comes at the expense of ductility. In this paper, a medium-carbon multiphase bainitic steel was produced through intercritical annealing (IA) at various temperatures, followed by isothermal bainite ...

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

Materials 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.

Effects of normalizing and tempering temperature on the bainite microstructure and properties of low alloy fire-resistant steel bars

High Temperature Materials and Processes
Different combinations of normalizing and tempering were carried out to optimize the microstructure and enhance the high-temperature mechanical properties of HRB400FR fire-resistant steel bars. The results showed that with the increasing of the tempering

Effect of Pipe Flattening in API X65 Linepipe Steels Having Bainite vs. Ferrite/Pearlite Microstructures

Metals, 2018
The influence of microstructure on pipe flattening response was assessed using two different commercially produced U-ing, O-ing, and expansion (UOE) pipes from API X65 steels having either a bainitic microstructure (steel B) or a ferrite/pearlite ...

Ultra-Fine Bainite in Medium-Carbon High-Silicon Bainitic Steel

Materials
The effects of austenitizing and austempering temperatures on the bainite transformation kinetics and the microstructural and mechanical properties of a medium-carbon high-silicon ultra-fine bainitic steel were investigated via dilatometric measurements, microstructural characterization and mechanical tests.
