The effect of hydrogen on the bainite transformation

Journal of Materials Science, 1999
The 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 ...

Influence of Co and Al on Bainitic Transformation in Super Bainitic Steels

steel research international, 2013
AbstractThe effect of cobalt and aluminum addition on the bainitic transformation of super bainitic steels was investigated. Nanostructured bainitic ferrite and retained austenite microstructures were obtained when the steels were transformed at low temperatures. The bainitic transformation was accelerated by the addition of Co and Al. The thickness of

Effects of ausforming strain on bainite transformation in nanostructured bainite steel

International Journal of Minerals, Metallurgy, and Materials, 2017
The 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 ...

The crystallography of the bainite transformation—I

Acta Metallurgica, 1968
Abstract 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.

Bainite Transformation in Deformed Austenite

Metallurgical and Materials Transactions A, 2010
This 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, 2011
Abstract 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, 2001
Abstract 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, 2017
A 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, 2008
Abstract 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.
