Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, EarlyView.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

General formulation for uniform and non‐uniform high‐strength steel slender I‐section beams

Steel Construction, EarlyView.
Abstract The Ayrton–Perry approach is the basis of Eurocode 3 rules for buckling resistance, with distinct curves and imperfection factors depending on section type, steel grade, and other parameters. For generic members – built‐up or not, uniform or not, with complex supports or not – the code allows either the general method (clause 8.3.4 of Eurocode

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Study on Welding Inherent Deformations in Welded Structural Materials

Study on Welding Inherent Deformations in Welded Structural Materials
It is meaningful to predict welding deformation in practical time and to apply these data in welding industry. In this paper, the inherent deformations of beading on plate welding and fillet welding are studied. A 3D thermal-elastic-plastic FEM based on interactive substructure method (ISM) is used to predict the welding deformations.

Strip loading in steel fiber reinforced concrete: Experimental and theoretical investigation

Structural Concrete, EarlyView.
Abstract Fiber reinforced concrete is becoming increasingly popular in engineering practice due to its high robustness, post‐cracking behavior, and crack control. For strip loading, as common, for example, in longitudinal joints of tunnel lining segments, the use of fiber reinforced concrete has the potential to reduce conventional reinforcement ...

Assessment of shear reinforcement enhancement on the punching shear capacity of flat concrete slabs with openings

Structural Concrete, EarlyView.
Abstract Reinforced concrete flat slabs are widely employed in contemporary architecture due to their structural efficiency and construction simplicity; however, their susceptibility to punching shear failure remains a critical design concern, particularly at slab–column connections where concentrated loads occur.
