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

Suppression Control of Transversal Oscillation on High‐Cycle Fatigue Properties of Thin Spot‐Welded Steel Sheets

Shock and Vibration, Volume 2026, Issue 1, 2026.
Resistance spot welding (RSW) is a critical joining technique in automotive manufacturing, where the fatigue performance of spot‐welded joints significantly influences the durability and structural integrity of vehicle bodies. The novelty of this study lies in systematically identifying and quantitatively controlling two major experimental disturbances,

The normal and shear strength properties of laser lap weld [PDF]

, 2019
The study was aimed to clarify the shear strength and the normal strength properties of the lap joint. The welds were characterized with respect to hardness, tensile and fatigue properties. The test materials of this study were low strength carbon steel (

Structural behaviour of HSS hollow section K‐joints – Experimental investigations and advanced numerical modelling using damage mechanics

Steel Construction, Volume 18, Issue 3, Page 164-179, September 2025.
Abstract Welded hollow section trusses are commonly used in structures such as pedestrian bridges and crane girders. High‐strength steels (HSS) enable increased load capacity and reduced weight, but their limited ductility restricts plastic stress redistribution, which is typically assumed in current design rules for mild‐strength steels (MSS) to ...

Evaluation of the Friction Coefficient for TRIP1000 Steel under Different Conditions of Lubrication, Contact Pressure, Sliding Speed and Working Temperature

Metals, 2022
The use of ultra-high-strength steels (UHSS) has been growing in recent years, mainly in the automotive industry. Since these steels have high strength and hardness, more applied stresses are required to deform them, probably also impacting friction ...

Modelling the post‐fire material behaviour of high‐ and ultra‐high‐strength steels

Steel Construction, Volume 18, Issue 2, Page 69-79, May 2025.
Abstract High‐strength steels can contribute to more sustainable and resource‐efficient constructions; for example, they can result in material savings due to the possibility of using smaller cross‐sectional dimensions. However, for a reliable assessment of the residual load‐bearing capacity of high‐strength steel components after a fire, there are ...

Study on Contact Characteristics of Cold Rolled Deformation Zone of Ultra-High-Strength Steel

Metals
This study investigates the longitudinal deformation behavior of ultra-high-strength steel (UHSS) during the cold rolling process. First, rolling experiments were conducted on UHSS, and longitudinal surface coordinates of the deformation zone were ...
