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.

Hydrogen diffusion and the percolation of austenite in nanostructured bainitic steel [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 The diffusion of hydrogen in austenite is slower than in ferrite. Experiments have been conducted to study the behaviour of hydrogen in a nanostructured steel sample consisting of a mixture of thin plates of bainitic ferrite and intervening films of retained austenite, with the latter phase present in a quantity larger than the percolation threshold, i.

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
