Producing Nanobainite on Carburized Surface of a Low-Carbon Low-Alloy Steel

Journal of Materials Engineering and Performance, 2022
Conducting the carburizing process on the surface layer of low-carbon steel and subsequent austempering heat treatment can be implemented to obtain nanobainite microstructure on the surface of steels. In this research, steel with 0.23 wt.% carbon was carburized for 3 h at 900 degrees C in a liquid salt bath containing sodium cyanide, sodium carbonate ...

Microstructures and properties of a novel carburizing nanobainitic bearing steel

Materials Science and Engineering: A, 2020
Abstract Nanobainite and dispersed carbides were gained on the surface layer of a modified carburizing 23Cr2Ni2Si1Mo bainitic bearing steel based on carburization, tempering at high temperature, and succedent low-temperature isothermal quenching. As compared with the conventional carburizing 20Cr2Ni4 martensitic bearing steel, the novel carburizing ...

A Preliminary Study on Machinability Assessment of Nanobainite Steel

Volume 2B: Advanced Manufacturing, 2013
The demand for high strength materials and improvements in heat treatment techniques has given rise to this new form of high strength steel known as nanobainite steel. The production of nanobainite steel involves slow isothermal holding of austenitic steel around 200°C for 10 days, in order to obtain a carbon enriched austenite and cooling to room ...

Crystallographic analysis of nanobainitic steels

Scripta Materialia, 2009
Electron back-scattered diffraction in conjunction with transmission electron microscopy was employed to investigate the crystallographic nature of bainitic laths formed at relatively low transformation temperatures where a nanostructured bainite forms.

Nanoscale microstructural characterization of a nanobainitic steel

Acta Materialia, 2011
Abstract A 0.79 C–1.5 Si–1.98 Mn–0.98 Cr–0.24 Mo–1.06 Al–1.58 Co (wt.%) steel was isothermally heat treated at 200 °C for 10 days and 350 °C for 1 day to form a nanoscale bainitic microstructure consisting of nanobainitic ferrite laths with high dislocation density and retained austenite films. The microstructures of the samples were characterized by
