Evaluation of the Possibility to Obtain Nanostructured Bainite in High-Carbon and High-Silicon 9XC Bearing Steel

Journal of materials engineering and performance (Print), 2020
The main aim of this research is the evaluation of the possibility of obtaining a nanostructured bainite after isothermal heat treatment of 9XC (according to GOST standard) bearing steel. It was found that the annealing at low temperature (250 °C) allows

Distribution of Dislocations in Nanostructured Bainite

Solid State Phenomena, 2011
The dislocation density in ferrite and austenite of a bainitic microstructure obtained by transformation at very low temperature (300 °C) has been determined using transmission electron microscopy. Observations revealed that bainitic ferrite plates consist of two distinctive regions with different substructures. A central region in the ferrite plate is

Feasibility study for thixoforming nanostructured bainitic steels [PDF]

Materials Science and Engineering: A, 2016
Abstract Super Bainite Steel (0.74% C, 1.64% Si, 1.82% Mn, 1% Ni, 0.36% Mo, 0. 21% Cr, 0.047% Al bal. Fe) after cold plastic deformation was used as the starting material for bainitic treatment preceded by controlled cooling from the thixoforming temperature range.

Enhanced thermal stability in nanostructured bainitic steel [PDF]

Scripta Materialia, 2013
We report an attempt at increasing the thermal stability of nanocrystalline bainite to tempering heat treatments by enhancing the silicon concentration of the alloy. Validation experiments have been conducted using synchrotron X-irradiation during tempering heat treatment. It is found that the change in alloying successfully stabilizes the austenite at

Development of advanced cementite-free bainitic steel using Ni, Al and Cu additions – Design concept and phase transformations study

Journal of Materials Research and Technology, 2023
A novel concept, consisting of the stabilization of retained austenite with Ni, Al, and Cu additions instead of using Si as the major alloying element to prevent carbide formation, is proposed to design nanocrystalline, cementite-free bainitic steels. In

Infusion of hydrogen into nanostructured bainitic steel [PDF]

Materials Characterization, 2017
The trapping of hydrogen in nanostructured bainitic steel has been investigated using thermal desorption analysis, in order to determine the potency of the ferrite-retained austenite (α/γ) interfaces and retained austenite as trapping sites. Thermal desorption data showed that the volume of retained austenite is more effective in trapping hydrogen than

Severe deformation of nanostructured bainitic steel

Procedia Engineering, 2017
Abstract Nanostructured bainite has been developed to meet the stringent demands of ballistic impacts. In a previous report [Y.T. Tsai et al., Scripta Mater. 2016;115:46], the deformation behavior of nanostructured bainite under high strain rate (2×103 s-1) was studied using a split Hopkinson pressure bar.
