Characterisation studies of linear friction welded titanium joints

Materials & Design, 2017
Abstract The microstructure and texture evolution during linear friction welding (LFW) of pure titanium joints were investigated with scanning electron microscope, transmission electron microscope and electron back-scattering diffraction. The unique combination of high temperatures and strain rates during LFW causes limited continuous dynamic ...

Numerical Prediction of Deformation‐Induced Martensitic Transformation in Cold‐Sprayed Austenitic Stainless Steel

steel research international, EarlyView.
Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

3D Modelling of Flash Formation in Linear Friction Welded 30CrNiMo8 Steel Chain

Metals, 2017
Linear friction welding (LFW) is a solid-state welding process that has been thoroughly investigated for chain welding in recent years in order to replace the currently in use Flash Butt Welding (FBW) process.

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.

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.

Experimental analysis of bolted connections for precast concrete walls under cyclic tensile loading

Structural Concrete, EarlyView.
Abstract Dry‐bolted connections in precast wall structures simplify the assembly process and offer significant advantages in terms of construction speed and cost. In fact, the reduction of the required workmanship, compared to wet connections, makes this solution highly competitive.
