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

open access: yessteel 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.

The Influence of Subcritical Annealing and Cold Working on the Hydrogen Embrittlement Susceptibility of X65 D Pipeline Steel

open access: yesMaterials and Corrosion, Volume 76, Issue 10, Page 1478-1496, October 2025.
This study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel. Hydrogen charging reduced the ductility of all specimens. Both subcritical annealing and cold working decreased somewhat the degree of HE.

Effects of the Wire Feeding Speed on the Mechanical Properties and Electrochemical Corrosion Behaviors of a Hybrid Laser-MAG Welded X90 Pipeline Steel

open access: yesInternational Journal of Electrochemical Science, 2020
This paper studies the welding of X90 pipeline steel with ER100S-G welding wire via laser-metal active gas arc (laser-MAG) hybrid welding and explores the effects of three wire feeding speeds (8.5 mm/s, 9 mm/s, and 9.5 mm/s) on the microstructure ...

Utilization of Non‐Metallic Inclusion to Induce Intragranular Acicular Ferrite Formation Contributing to “Oxide Metallurgy”: Effect of Ti/Al Content on the Microstructure Evolution

open access: yessteel research international, Volume 96, Issue 8, August 2025.
Fine size inclusion can serve as the effective nucleation site to induce the formation of optimal microstructure, i.e. intragranular acicular ferrite (IAF). Here, the low‐alloy steels with different amounts of Ti and Al contents are prepared, and the inclusion characteristics are quantitatively investigated.

Studies on Preparation of Acicular Ferrites and Their Properties.

open access: yesJournal of the Japan Society of Powder and Powder Metallurgy, 1998
Acicular barium ferrite, cobalt ferrite and crystal oriented manganese zinc ferrite particles were prepared using the acicular α-FeOOH as the starting material. The crystal structure and magnetic characteristics of these fine particles were investigated in detail. Acicular barium ferrite fine particles doped with Co2+ ions and Ti4+ ions were fabricated

Reduction of Basic Iron Ore Sinter under Blast Furnace Wall and Center‐Simulated Conditions in CO–CO2–H2–H2O–N2 Gas

open access: yessteel research international, Volume 96, Issue 7, July 2025.
This study investigates the reduction of iron ore sinter in hydrogen and water vapor‐containing gas. It reveals differences in reduction behavior between blast furnace center and wall regions. Results highlight the role of temperature, gas composition, and microstructure in reduction efficiency.

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

open access: yesFatigue &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.
