Effect of ferrite-to-austenite phase transformation path on the interface crystallographic character distributions in a duplex stainless steel
TL;DR: In this paper, the effect of the ferrite to austenite phase transformation route on the microstructure and interface plane character distributions was studied in a duplex stainless steel, and two markedly different austenitic morphologies (i.e., equiaxed and Widmanstatten) were produced through diffusional (slow cooling) and semi-shear (air-cooling) transformations, respectively.

The combining effects of ausforming and below-Ms or above-Ms austempering on the transformation kinetics, microstructure and mechanical properties of low-carbon bainitic steel

TL;DR: In this article, the isothermal transformation kinetics, microstructure and mechanical properties of a low-carbon bainitic steel, subjected to below-Ms/above-Ms austempering with or without prior ausforming, have been investigated via dilatometric measurements, microstructural characterization and mechanical tests.

Accelerating nano-bainite transformation based on a new constructed microstructural predicting model
TL;DR: In this article, an accurate black-box model that could predict the plate thickness of bainitic ferrite was constructed based on gradient boosting decision tree model, and a polynomial model was constructed to make predicting process easier.

Carbon microalloying effect of base material on variant selection in coarse grained heat affected zone of X80 pipeline steel
TL;DR: In this paper, the carbon microalloying effect of base material on the crystallographic structure of coarse grained heat affected zone (CGHAZ) of X80 girth welded joints was systematically investigated using electron back-scattering diffraction (EBSD).
Journal ArticleDOI
Effect of Prior Austenite Grain Size on the Morphology of Nano-Bainitic Steels
TL;DR: In this paper, the morphology of bainitic ferrite in Fe-0.89C-1.59Si-Si 1.19Cr (wt-pct) bainite steel has been investigated as a function of the prior austenite grain size (AGS).

Bainite in Steels
TL;DR: The mechanism of the bainite transformation in steels is reviewed in this paper, with a summary of the early research and concluding with an assessment of the transformation in the context of the other reactions which occur as austenite is cooled to temperatures where it is no longer the stable phase.

Crystallographic features of lath martensite in low-carbon steel
TL;DR: In this article, electron backscattering diffraction with field-emission scanning electron microscopy was used to analyze crystallographically the lath martensite structure in a 0.20% carbon steel.

The determination of foil thickness by scanning transmission electron microscopy
TL;DR: In this article, a simple and accurate method of determining foil thickness is described, which makes use of measurements of the spacing of intensity oscillations in convergent beam diffraction patterns obtained with commercial scanning transmission electron microscopes.

Acceleration of Low-temperature Bainite
TL;DR: In this article, the authors report methods for accelerating the rate of reaction without compromising strength, and show that bainitic ferrite plates produced by transformation at low temperatures can be as thin as 20 nm with a hardness in excess of 650 HV.
