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

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-

Assessing the Very High Cycle Fatigue Behavior and Frequency Effect of Structural Steel Welds

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 4, Page 1529-1541, April 2025.
ABSTRACT The very high cycle fatigue behavior of S275J2+N flux‐core arc welded joints was investigated using the ultrasonic fatigue testing method at a loading frequency of 20 kHz. A bespoke specimen design featuring the weld toe was employed to more suitably represent in‐service welded joints than typical ultrasonic fatigue testing specimens.
