Effect of austempering conditions on the microstructure and mechanical properties of AISI 4340 and AISI 4140 steels

Journal of Materials Research and Technology, 2019
AISI 4340 and AISI 4140 are normally used for different structural applications in quenched and tempered state due to their high strength, high abrasion and fatigue resistance but they lack toughness. Presence of dual phase microstructure such as ferrite-

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

Thermomechanical Processing, Microstructure, and Mechanical Properties of Medium‐Mn Steel

steel research international, Volume 96, Issue 12, Page 252-260, December 2025.
The microstructure evolution and mechanical properties of a medium‐Mn steel are investigated after thermomechanical processing and isothermal holding at various temperatures. A fine multiphase structure of bainite, fresh or tempered martensite, and retained austenite are obtained.

Enhancing strength without sacrificing ductility in medium-carbon multiphase bainitic steel through increased intercritical annealing temperatures

Journal of Materials Research and Technology
In bainitic steels, enhancing strength often comes at the expense of ductility. In this paper, a medium-carbon multiphase bainitic steel was produced through intercritical annealing (IA) at various temperatures, followed by isothermal bainite ...

Phase-field analysis of quenching and partitioning in a polycrystalline Fe-C system under constrained-carbon equilibrium condition

, 2018
Mechanical properties of steels are significantly enhanced by retained austenite. Particularly, it has been shown that a recently developed heat-treatment technique called Quenching and Partitioning (Q\&P) stabilises austenite effectively. In the present
