Continuous Cooling Transformation Behaviour and Bainite Transformation Kinetics of 23CrNi3Mo Carburised Steel [PDF]

open access: yesMetals, 2020
In this study, the phase transformation behaviour of the carburised layer and the matrix of 23CrNi3Mo steel was comparatively investigated by constructing continuous cooling transformation (CCT) diagram, determining the volume fraction of retained ...

BAINITE : OVERALL TRANSFORMATION KINETICS

open access: yesLe Journal de Physique Colloques, 1982
New experimental results on the overall transformation kinetics of the bainite reaction (in three different steels) are interpreted in terms of recent work on the transformation mechanism of bainite.

Study on Kinetics of Transformation in Medium Carbon Steel Bainite at Different Isothermal Temperatures [PDF]

open access: yesMaterials, 2021
Ultra-fine carbide-free bainitic (UCFB) steel, also known as nano-bainite (NB) steel, is composed of bainitic ferrite laths with nanoscale thickness and carbon-rich film-like retained austenite located between laths.

A new physical model for the kinetics of the bainite transformation

open access: yesISIJ International, 2006
A model describing the bainite reaction is presented that takes into account the effect of very small austenite grain size. This model considers the displacive approach and uses thermodynamic criteria for the description of the nucleation and growth of ...

Kinetics of bainite transformation in heterogeneous microstructures

open access: yesMaterials Letters, 2012
International audienceIn classical models for microstructural evolution, the natural dispersion existing in the samples is often neglected. In this paper, we propose a general procedure that takes into account the distribution of austenite grain size on ...

New model for the overall transformation kinetics of bainite. Part 1: The model [PDF]

open access: yesMATERIALS TRANSACTIONS, 2013
A new model for the overall transformation kinetics of bainite has been developed. Based on the displacive mechanism for the bainite transformation, the model distinguishes between the nucleation kinetics of bainitic ferrite in prior austenite grain ...

Kinetics of bainite transformation in steels

open access: yes, 2012
The main kinetic features of the formation of bainite are discussed, firstly in relation to two incompatible hypotheses for the growth mechanism of bainitic ferrite.

Study of bainitic transformation kinetics in SAE 52100 steel

open access: yesJournal of Materials Research and Technology, 2019
The objective of this research was to investigate the bainitic formation in austempered SAE 52100 steel. The original microstructure of SAE 52100 steel consisted of spheroidized pearlite.

New insights into the effects of deformation below-MS on isothermal kinetics of bainitic transformation

open access: yesJournal of Materials Research and Technology, 2020
Both ausforming and austempering below the martensite start temperature (MS) have been shown to accelerate the bainitic transformation. This work investigates the combined effects of deformation and austempering below the MS on the isothermal ...

Mathematical Modelling of Bainite Transformation Kinetics [PDF]

open access: yesLe Journal de Physique IV, 1997
Steels with a mixed microstructure of allotriomorphic ferrite, bainitic ferrite, retained austenite and martensite have potentially good combinations of high strength and formability. This work describes a kinetic theory for the formation of bainite in steels where the precipitation of carbides is suppressed.
