Microstructure Development in a New Generation S1300‐Type Ultrahigh‐Strength Structural Steel on Tempering

steel research international, Volume 97, Issue 1, Page 524-542, January 2026.
Here, the microstructure evolution of a new generation ultrahigh‐strength S1300‐type structural steel has been investigated for direct‐quench and tempering route. Various stages of tempering are elucidated by thorough characterization, and a new strain‐size parameter of martensite is proposed to have a correlation with hardness, which will be useful in

Austempering Post‐Intercritical Austenitizing to Enhance Mechanical Properties of an Oil Country Tubular Goods Steel

steel research international, Volume 96, Issue 12, Page 211-227, December 2025.
A new austempering approach following intercritical austenitizing is explored to improve the mechanical behavior of API 5CT steel. By tailoring ferrite–bainite microstructures, the process achieves a balance of strength and ductility without the need for post‐quench tempering. The results highlight a cost‐effective alternative to conventional quenching

Thermo-kinetic understanding of the correlation between bainitic transformation and mechanical properties for bainitic steels

Journal of Materials Research and Technology
Phase transformations are feasible approaches for tailoring microstructures to achieve desired mechanical properties. However, the direct link between phase transformations and mechanical properties remains poorly studied. Here, using the theory of generalized stability (GS), we theoretically and experimentally correlate the bainitic transformation ...

Austenite-Bainite Transformation Kinetics in Austempered AISI 5160 Steel

European Scientific Journal, ESJ, 2018
This research investigates the process of the formation of bainite in austempered 5160 steel. Steel bar samples were austenitized at 1128 K for 20 minutes followed by holding at various times from 10 seconds to 2 hours and isothermal temperatures from 561K to 728K to obtain a multi-phase matrix.
