Glow discharge nitriding of nanobainitic X37CrMoV5-1 steel
, 2023 Abstract One of the methods of improving mechanical properties of steels is nanostructuring via austempering, which leads to formation of a nanobainitic microstructure - a fine carbide-free bainitic ferrite plates with retained austenite. Due to high density of grain and interphase boundaries, this microstructure provides high tensile strength.

METHOD OF OBTAINING NANOBAINITE IN STEELS : MODERN TECHNOLOGIES
Ukrainian Journal of Civil Engineering and ArchitectureStatement of the problem. Trends in the development of engineering materials show a steady tendency toward increasing strength, toughness, and ductility. This is especially evident for steels, as they compete with lightweight alloys and composite materials in many fields of application.

Effect of prior martensite on the thermal stability of nanobainitic steels
Materials Research Express, 2019 Two types of the nanobainitic microstructures which consist of plate-like bainitic ferrite, retained austenite with and without martensite were obtained by quenching to Ms-12 °C and ausforming by about 30% before isothermal bainitic transformation at 300 °C.

A superior strength and sliding-wear resistance combination of ductile iron with nanobainitic matrix
Journal of Materials Research and Technology, 2021 A nanobainitic matrix composing of nanoscale α phase and carbon-riched γ phase was obtained for the ductile iron by austempering treatment. The microstructure and properties of ductile iron were compared with GCr15. The microstructural characteristic gave rise to a good strength with an ultimate tensile strength higher than 1200 MPa, which was ...

Effect of chemical segregation on nanobainitic transformation in laser cladded coatings
Materials & Design, 2015 Abstract Laser cladding and subsequent isothermal holding were employed to fabricate the Fe-based nanobainitic coatings. The microstructures of the isothermal heat treated coatings were observed and characterized by using the optical microscope (OM), filed-emission scanning electron microscope (FE-SEM), field-emission transmission electron microscope

Corrosion Resistance of The Bearing Steel 67SiMnCr6-6-4 with Nanobainitic Structure
Archives of Metallurgy and Materials, 2015 AbstractThe paper describes a comparative study of the corrosion resistance of bearing steel 67SiMnCr6-6-4 after two kinds of nanostructuring treatments and two kinds of conventional quenching and tempering treatments. The nanostructuring treatment consisted of austempering with an isothermal quenching at 240°C and 300°C.
