Crystallography of carbide-free bainite in a hard bainitic steel

Materials Science and Engineering: A, 2006
The convergent beam Kikuchi line diffraction technique has been used to accurately determine the orientation relationships between bainitic ferrite and retained austenite in a hard bainitic steel. A reproducible orientation relationship has been uniquely observed for both the upper and lower bainite.

The mechanism of bainite transformation in steels

Scripta Materialia, 2002
Abstract Sympathetic nucleation and ledgewise growth are competitive with each other throughout the bainite formation in steels. Many evidences are provided to support this mechanism as follows: ultra-fine structures of bainite and its surface relief, and carbide nucleation inside austenite at the interface of ferrite/austenite, etc.

The bainite transformation in a silicon steel

Metallurgical Transactions A, 1979
An experimental silicon steel has been used in a detailed kinetic and structural study of the bainite transformation in an attempt to resolve some of the controversies concerning the reaction mechanism. Distinct reaction ‘C’ curves and transformation mechanisms were observed for the upper and lower bainite reactions. The observed set of three minima in

Ferrite and bainite in alloy steels

Metallurgical Transactions, 1972
The addition of alloying elements even in small concentrations can alter the properties and structure of ferrite and bainite. The various morphologies of ferrite-carbide aggregates are surveyed including alloy pearlite, fibrous carbide eutectoids and precipitation of fine alloy carbides atγ-α interfaces.

Effect of bainite fraction on hydrogen embrittlement of bainite/martensite steel

Materials Science and Engineering: A, 2021
Abstract The paper quantifies how the fraction of bainite in dual-phase (bainite/martensite) steel affects its resistance to hydrogen embrittlement (HE). For this purpose, three steels that had different amounts (0, 0.9, and 1.8 wt%) of nickel were used.

Caviation erosion of bainitic steel

Wear, 1998
Abstract The cavitation erosion of a bainitic steel in distilled water has been investigated by means of a rotating-disc erosion apparatus. It was found that the bainitic steel specimen with higher value of impact toughness has better cavitation resistance and the increase of the relative content of lower bainite can improve the cavitation resistance

An overview on bainite formation in steels

Current Opinion in Solid State and Materials Science, 2005
The present report makes an attempt to review some studies by Chinese researchers on bainite in steel from the viewpoint of thermodynamics, kinetics, crystallography, microstructure, mechanism, etc. Due to the complexity of bainite transformation in steels, the extensive disagreement between the diffusion school and the shear school on bainite ...

Strengthening mechanisms in bainitic steels

Acta Metallurgica, 1971
Abstract An investigation has been made of the microstructures and mechanical properties of a series of 1%Cr-0.5 %Mo-0.002%B base steels following isothermal transformation to structures of the granular, upper and lower bainite types. The results indicate that in granular bainites the strength is raised above the base level of the matrix by the ...

Annealing of a Nanostructured Bainitic Steel

Metallography, Microstructure, and Analysis, 2020
Abstract This article describes a procedure for optimizing the annealed microstructure of a high Al KAB steel. The main focus is directed toward characterization of microstructural development during annealing of different phases in a nanostructured bainitic steel using high resolution transmission electron microscopy (HRTEM).
