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.

steel research international, Volume 92, Issue 6, June 2021., 2021 A new medium manganese steel with vanadium addition for automotive forging application is presented. The steel is alloyed with 4 wt% aluminum to assure a complete martensitic microstructure after air‐cooling. The investigated laboratory melt (80 kg), reaches a yield strength of 892 MPa and a Charpy‐V notch impact toughness of 48 J in the air‐cooled ...

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

The substitution of aluminum for cobalt in nanostructured bainitic steels [PDF]
AIP Conference Proceedings, 2018 Two kinds of new steels are designed, in which the only difference is the use of the alloy element aluminum instead of cobalt. The effect of cobalt and aluminum addition on the microstructure and mechanical properties of high-carbon nanostructured bainitic steels was studied. The microstructure and mechanical properties achieved by a low temperature au
