Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

steel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Identification of invisible damage in prestressed concrete bridges—A demonstrator case using coda wave interferometry

Structural Concrete, EarlyView.
Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.

Experimental and analytical investigations on the effect of steel fibers on the crack behavior and strength of dapped‐end connections

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) dapped‐end connections feature a sharp re‐entrant corner subjected to high stress concentrations, leading to wide cracks under service loads and potential durability issues such as reinforcement corrosion. Effective crack control is therefore essential in the design of new dapped‐end connections. Steel fiber reinforced

Side‐by‐side long‐term performance assessment of GFRP‐ and steel‐reinforced concrete bridge decks

Structural Concrete, EarlyView.
Abstract The corrosion‐induced deterioration of steel‐reinforced bridge decks is a service life concern, especially in cold regions, where the use of deicing chemicals is common. To address this issue, glass fiber‐reinforced polymer (GFRP) reinforcement has received growing attention, owing to the GFRP's resistance to conventional corrosion.
