Understanding of the Bainite Transformation in a Nano-Structured Bainitic Steel
Solid State Phenomena, 2011A 0.79C-1.5Si-1.98Mn-0.98Cr-0.24Mo-1.06Al-1.58Co (wt%) steel was isothermally heat treated at 200°C for 10 days to form a nano-scale bainitic microstructure consisting of nanobainitic ferrite laths with high dislocation density and retained austenite films.

Crystallography of carbide-free bainite in a hard bainitic steel
Materials Science and Engineering: A, 2006The 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, 2002Abstract 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, 1979An 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, 1972The 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.

Annealing of a Nanostructured Bainitic Steel
Metallography, Microstructure, and Analysis, 2020Abstract 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).

The mechanism of bainite formation in steels
Acta Metallurgica, 1980Abstract New microstructural evidence, together with a thermodynamic analysis, of the bainite reaction in steels are presented in support of a growth mechanism involving the propagation of displacive sub-units. The results are shown to be consistent with a displacive mechanism, rather than with one involving reconstructive growth. It is also possible
