Effects of ausforming strain on bainite transformation in nanostructured bainite steel

International Journal of Minerals, Metallurgy, and Materials, 2017
The effects of ausforming strain on bainite transformation in high-carbon low-alloy nanobainite steel were investigated using a Gleeble 3500 thermomechanical simulator machine. The bainite transformation speed at 300°C was found to be accelerated by ausforming at 300, 600, and 700°C under applied strains ranging from 10% to 50% followed by isothermal ...

Microstructural characterization of Charpy-impact-tested nanostructured bainite

Materials Characterization, 2015
Abstract In this work, a possible cause of the extraordinary low impact toughness of nanostructured bainite has been investigated. The microstructure of nanostructured bainite consisted chiefly of carbide-free bainitic ferrite with retained austenite films.

Microstructural Characteristics and Mechanical Properties of Nanostructured Bainite Processed through High and Low Temperature Ausforming and Isothermal Holding near Ms in a Medium Carbon Steel

Materials Science Forum, 2023
Laboratory rolling simulations, comprising of thermomechanically controlled rolling followed by ausforming and isothermal holding close to Ms temperature, were conducted on a medium-carbon (C) steel in order to understand the combined effect of prior ...

Effect of nickel on hardening behavior and mechanical properties of nanostructured bainite-austenite steels

, 2021
Ni-free and Ni-bearing steels were designed to elucidate the effect of Ni on the free energy of bainitic transformation. Steels with two distinct nano-bainite structures were obtained through conventional one-stage and two-stage isothermal treatments ...

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.
