Effects of ausforming strain on bainite transformation in nanostructured bainite steel
International Journal of Minerals, Metallurgy, and Materials, 2017The effects of ausforming strain on bainite transformation in high-carbon low-alloy nanobainite steel were investigated using a Gleeble 3500 thermomechanical simulator machine. The bainite transformation speed at 300°C was found to be accelerated by ausforming at 300, 600, and 700°C under applied strains ranging from 10% to 50% followed by isothermal ...

Bainite transformation in deformed austenite
Metallurgical Transactions A, 1976In this work the effect of deformation of metastable austenite on its subsequent isothermal decomposition in bainite regions was investigated in three chromium steels with varying carbon contents. Four different types of treatments were used and the effect of carbon content was studied.

The bainite transformation: unresolved issues
Materials Science and Engineering: A, 1999Abstract A great deal of research, over many decades since the discovery of bainite, has revealed substantial information about the mechanism of the bainite transformation in steels. Elements of the theory are now routinely being used in many parts of the world in the design of novel alloys and in the interpretation of a variety of experimental data.

The crystallography of the bainite transformation—I
Acta Metallurgica, 1968Abstract The crystallography of the bainite transformation in an Fe-8% Cr-1.1 % C alloy was studied. Measurements of the habit plane by two-surface analysis and the specific variant of the orientation relationship have been made for the first time for a lower bainite transformation.

The effect of hydrogen on the bainite transformation
Journal of Materials Science, 1999The effect of hydrogen on the upper bainite transformation in two silicon containing steels has been investigated. For comparison, isothermal transformation at the same temperature has also been performed in a helium atmosphere. In both Fe-0.2C-3Mn-2Si and Fe-0.4C-4Ni-2Si (nominal wt %) alloys it was discovered that the bainite reaction proceeds ...

Bainite Transformation in Deformed Austenite
Metallurgical and Materials Transactions A, 2010This study documents the characteristics of bainite transformations in deformed austenite during continuous cooling of a low-carbon microalloyed steel. In particular, it describes the distinguishing features of the two types of bainite observed: conventional bainite (CB) and acicular ferrite (AF).

Evolution of transformation plasticity during bainitic transformation
International Journal of Materials Research, 2011Abstract The influences of prior austenitization treatment and the state of applied stresses on the evolution of transformation plasticity strains during isothermal bainitic phase transformation and the resulting microstructures were examined.

Bainitic transformation kinetics and stress assisted transformation
Materials Science and Technology, 2001Abstract With reference to experimental data, the effects of stress, chemical composition, and transformation temperature on bainitic transformation kinetics are analysed. A decrease of transformation temperature or an increase of carbon equivalent results in a slow rate of bainitic transformation and reduces the promotive effect of stress induced ...

Analysis on bainite transformation in reheated low-carbon bainite weld metals
Materials Science and Technology, 2017A combination of laser scanning confocal microscopy (LSCM) and dilatometry was utilised to simultaneously qualitatively analyse the morphological evolution of bainite by examination of in situ observed micrographs and to quantitatively investigate the amount of bainite transformation by studying dilatometry data.

Bainite Sensor – A new tool for process and quality control of the bainite transformation*
HTM Journal of Heat Treatment and Materials, 2008Abstract A non-destructive online measurement system called “Bainite Sensor” is developed for the application of monitoring bainite transformation in salt bath adapted heat treatment equipments, nowadays controlled by computer assisted features. The measurement procedure is based upon eddy current harmonic analysis.
