Transferring Nanoscale Bainite Concept to Lower C Contents: A Perspective

Metals, 2017
The major strengthening mechanisms in bainitic steels arise from the bainitic ferrite plate thickness rather than the length, which primarily determines the mean free slip distance.

Effect of austempering temperature on the microstructure and wear resistance of ultrafine bainitic steel

工程科学学报, 2018
Ultrafine bainitic steels, which are derived from nanostructured carbide-free bainitic steels, exhibit a remarkable combination of ultra-high strength and toughness together with excellent wear resistance. Their excellent integrated mechanical properties

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 ...

Impact of Partitioning Temperature Parameters during the Quenching and Partitioning Process on Medium Carbon Steels with Two Different Alloying Strategies

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 ...

Formation of Bainite in a Low‐Carbon Steel at Slow Cooling Rate – Experimental Observations and Thermodynamic Validation

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

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.
