Effect of Electropulsing on Nanostructured Bainitic Steel

Journal of Materials Engineering and Performance, 2021
Novel steel of Fe-0.81C-1.9Mn-1.48Si-0.27Mo-0.95Ni-1.43Co-0.79Al composition was austenitized at 930 °C and isothermally treated at 240 °C for different intervals of time to produce carbide-free nanostructured bainite. The metastable austenite transformed to nanostructured bainite without any carbide precipitation.

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).

Developing very hard nanostructured bainitic steel

Materials Science and Engineering: A, 2013
Abstract 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, 2016
Hydrogen 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.

Toughness variations in nanostructured bainitic steels

Materials Science and Engineering: A, 2012
Abstract 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

Deformation mechanisms in nanostructured bainitic steels under torsion

Materials Science and Engineering: A, 2020
Abstract A clean high carbon steel was made using vacuum induction melting and three distinct nanostructures were obtained by austempering it at 250, 300 and 350 °C respectively after a similar austenitization treatment at 950 °C. A decrease in austempering temperature causes refinement of bainitic ferrite (BF) as well as retained austenite (RA ...
