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

International Journal of Energy Research, Volume 2026, Issue 1, 2026.Cryogenic liquid hydrogen (LH2) and high‐pressure compressed gaseous hydrogen (CGH2) vessels are the core technologies for large‐scale hydrogen storage. This review systematically examines their design challenges and failure mechanisms under extreme cryogenic and high‐pressure conditions. For LH2 vessels, recent advances in thermal insulation, boil‐off

steel research international, Volume 96, Issue 6, June 2025.The study investigates microstructural evolution during high‐temperature partitioning in medium‐carbon, high‐silicon aluminum‐aided steels, exploring phase transformations affecting the final microstructure. Quenching and partitioning processes, with varying primary martensite fractions, reveal significant austenite stabilization at 350 °C, but ...

steel research international, Volume 96, Issue 2, February 2025.A low‐carbon (0.23 wt%) carbide‐free bainitic steel is successfully developed with a total alloying addition of 4.9 wt%, which is relatively lower than alloying additions reported in similar category of steels. The present findings indicate that the currently designed low‐alloy steel composition is amenable to generation of nearly carbide‐free bainitic

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.

Strengthening and mechanical stability mechanisms in nanostructured bainite [PDF]
Journal of Materials Science, 2013 Understanding the main relationships between the microstructure parameters controlling the strength and ductility of low temperature bainitic microstructures is of considerable importance for further development of these grades. Although the microstructure essentially consists of solely two phases, bainitic ferrite and retained austenite, the ...
