Extremely high strength achievement in medium-C nanobainite steel [PDF]
Scripta Materialia, 2018 Abstract Nanobainite was produced in medium-C Si-rich steel through ausrolling at 500 °C and subsequent austempering at temperatures slightly above the martensite start temperature. The tensile properties were studied and compared to high-C nanobainite steels.

Replacing martensite with nanobainite in moderately alloyed carburised steel for better wear performance [PDF]
International Journal of Materials Research, 2019 Abstract Nanobainitic structures were produced in a low alloy carburised steel at temperatures of 200, 250 and 300°C. Scanning electron microscope micrographs indicated bainitic ferrites formed with a thickness range of 30–150 nm. Wear test results revealed that the coefficient of friction for nanobainitic samples was smaller and ...

Effect of Deep Cryogenic Treatment on the Microstructure and Wear Resistance of a Novel Nanobainite Steel [PDF]
Steel Research International, 2021 A novel nanobainitic (NB) steel is treated by three different heat treatment routes: quenching‐tempering (QT), quenching‐austempering‐tempering (AT), and quenching‐austempering‐deep cryogenic treatment‐tempering (ACT). To investigate the effects of retained austenite (RA) with different morphologies, stabilities, and volume fractions on the wear ...

Effects of ausforming temperature on bainite transformation, microstructure and variant selection in nanobainite steel [PDF]
Acta Materialia, 2013 Abstract The bainite transformation behavior after plastic deformation of austenite, i.e., ausforming was studied by in situ neutron diffraction and ex situ experiments, and the effects of ausforming temperature was made clear. Ausforming, at a low temperature (573 K) was found to accelerate bainite transformation and produce a characteristic ...

Review of Nanobainite Steel Welding
Advanced Materials Research, 2012Nanobainite steel is a new strong structural material with an ultimate tensile strength of 2500 MPa, and toughness in excess of 30-40 MPam1/2. However, so far, no suitable methods can realize its welding because of poor weldabilities. This paper reviews recent researches on welding of nanobainite steel and points out their merits and demerits.

Crystallographic analysis of nanobainitic steels
Scripta Materialia, 2009Electron 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.

Effect of prior martensite on bainite transformation in nanobainite steel
Acta Materialia, 2015Abstract Nanobainite transformation behavior was comparably studied using in situ neutron diffraction measurements, scanning electron microscopy and electron backscatter diffraction observations for two heat treatments: with and without partial quenching before isothermal holding at 523 or 573 K.

Nanoscale microstructural characterization of a nanobainitic steel
Acta Materialia, 2011Abstract 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

Microstructures and properties of a novel carburizing nanobainitic bearing steel
Materials Science and Engineering: A, 2020Abstract 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 ...
