Bainitic Ferrite Plate Thickness Evolution in Two Nanostructured Steels. [PDF]
Materials (Basel), 2021 Bainitic ferrite plate thickness evolution during isothermal transformation was followed at the same holding temperatures in two nanostructured steels containing (in wt.%) 1C-2Si and 0.4C-3Si. A dynamic picture of how the bainitic transformation evolves was obtained from the characterization of the microstructure present at room temperature after full ...

Effect of Austenitising Temperature on Mechanical Properties of Nanostructured Bainitic Steel. [PDF]
Materials (Basel), 2017 Nanostructured bainite was obtained in high-carbon Si-Al-rich steel by low-temperature (220–260 °C) isothermal transformation after austenitisation at different temperatures (900 °C, 1000 °C, and 1150 °C). Improved strength-ductility-toughness balance was achieved in the nanostructured bainitic steel austenitised at low temperatures (900 °C and 1000 °C)

Novel Approach of Nanostructured Bainitic Steels' Production with Improved Toughness and Strength. [PDF]
Materials (Basel), 2020 The tendencies of development within the field of engineering materials show a persistent trend towards the increase of strength and toughness. This pressure is particularly pronounced in the field of steels, since they compete with light alloys and composite materials in many applications.

Rolling Contact Fatigue Performances of Carburized and High-C Nanostructured Bainitic Steels. [PDF]
Materials (Basel), 2016 In the present work, the nanostructured bainitic microstructures were obtained at the surfaces of a carburized steel and a high-C steel. The rolling contact fatigue (RCF) performances of the two alloy steels with the same volume fraction of undissolved carbide were studied under lubrication.

A Constitutive Relationship between Fatigue Limit and Microstructure in Nanostructured Bainitic Steels. [PDF]
Materials (Basel), 2016 The recently developed nanobainitic steels show high strength as well as high ductility. Although this combination seems to be promising for fatigue design, fatigue properties of nanostructured bainitic steels are often surprisingly low. To improve the fatigue behavior, an understanding of the correlation between the nanobainitic microstructure and the

Hydrogen Susceptibility of Nanostructured Bainitic Steels [PDF]
Metallurgical and Materials Transactions A, 2015 Abstract Nanostructured steels with an ultimate tensile strength of 1.6 GPa were produced with austenite content varying from 0 to 35 vol pct. The effect on the mechanical properties was assessed after saturating the steel with hydrogen. Elongation was reduced to 2 to 5 pct and UTS to 65 to 70 pct of prior value.
