Nanostructured Carbide-Free Bainite Formation in Low Carbon Steel [PDF]

Acta Metallurgica Sinica (English Letters), 2020
It is an important challenge to reduce the carbon content in nanostructured bainitic steels for commercialization purposes while still being able to gain the desired microstructural characteristics in nanoscale and not to deteriorate the strength–ductility combinations.

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.

Degradation of nanostructured bainitic steel under rolling contact fatigue [PDF]

Materials Science and Engineering: A, 2014
Abstract The consequences of rolling contact fatigue on a carbide-free nanostructured bainitic steel intended for bearing applications are presented for the first time. Tests performed at various intervals followed by mechanical, microscopical, and crystallographic characterization lead to the conclusion that the degradation mechanism is ductile void

Nanostructured Bainite-Austenite Steel for Armours Construction

Archives of Metallurgy and Materials, 2014
Abstract Nanostructured bainite-austenite steels are applied in the armours construction due to their excellent combination of strength and ductility which enables to lower the armour weight and to improve the protection efficiency. Mechanical properties of the bainite-austenite steels can be controlled in the wide range by chemical composition and ...

Retained austenite thermal stability in a nanostructured bainitic steel [PDF]

Materials Characterization, 2013
The unique microstructure of nanostructured bainite consists of very slender bainitic ferrite plates and high carbon retained austenite films. As a consequence, the reported properties are opening a wide range of different commercial uses. However, bainitic transformation follows the T0 criteria, i. e.

Constitutive Modeling of High-Strength Steel Designed for Ballistic Protection

EPJ Web of Conferences, 2018
Constitutive behaviour of a high-strength nanostructured bainitic steel NANOS-BA® was investigated in the article. A few types of mechanical tests under varying strain rates were carried out to determine the values of constants of Johnson-Cook flow and ...
