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).

Regeneration technique for welding nanostructured bainite
Materials & Design, 2013Abstract High-carbon steels which are transformed into extremely fine bainite plates embedded in a matrix of carbon-enriched austenite have recently been developed, and have found commercial application in the manufacture of engineering components. However, because of the large carbon concentration, they cannot be welded and this limits the scope for

Developing very hard nanostructured bainitic steel
Materials Science and Engineering: A, 2013Abstract Novel nanostructured high carbon high silicon, carbide-free bainitic steels with very high strength and good ductility have been developed in the recent decade. In this work, an alloy with a high carbon content and no manganese was designed and cast. The prepared samples were heat treated through an austempering process in the range 200–350 °

Hydrogen Permeation in Nanostructured Bainitic Steel
Metallurgical and Materials Transactions A, 2016Hydrogen permeation of nanostructured bainitic steel, produced at two different transformation temperatures, i.e., 473.15 K (200 °C) BS-200 and 623.15 K (350 °C) BS-350, was determined using Devanathan–Stachurski hydrogen permeation cell and compared with that of mild steel.

Distortion in 100Cr6 and nanostructured bainite
Materials & Design, 2012A series of experiments on 100Cr6 and a nanostructured carbide-free bainitically transformed steel are performed. The effect of heat treatment conditions on the degree of distortion due to phase transformation is established. By transforming bainitically other than martensitically, cooling rate plays a major role in decreasing distortion by one order ...

Low-temperature nanostructured bainite transformation: The effect of magnetic field
Materials letters (General ed.), 2019We have elucidated the determining role of high magnetic field on low-temperature nanostructured bainite transformation at an isothermal temperature of 300 °C. The application of 12 Tesla magnetic field increased the bainite volume percentage by 193% and

Toughness variations in nanostructured bainitic steels
Materials Science and Engineering: A, 2012Abstract Outstanding combination of strength and ductility in nanostructured bainitic steels makes them prone to be used as an important engineering material. However, there is still a necessity to investigate their toughness and effective parameters. This work aims to study the fracture toughness of these group of high strength carbide free bainitic

Nanostructured bainitic steel obtained through austempering or bainitic transformation of high Si steels consists of bainitic ferrite and carbon‐enriched retained austenite. Secondary tempering of those microstructures tailors their mechanical properties
