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

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.

Influence of Ausforming on the Micro‐ and Nanostructure of PH 13‐8 Mo Maraging Steels
steel research international, Volume 95, Issue 8, August 2024.The potential of the integration of ausforming into the heat treatment of PH 13‐8 Mo maraging steels is investigated. By performing ausforming, a refinement of martensite is achieved. Furthermore, the high number of induced nucleation sites can elevate the number density of β‐NiAl precipitates after aging.
