Effect of a Zn interlayer on dissimilar FSSW of Al and Cu

Materials & Design, 2017
Abstract The present paper focuses on the role played by a Zn interlayer in the improvement of the mechanical behavior of Al-Cu Friction Stir Spot Welds. An unusual configuration of lap joint with Cu at the top surface as well as rather thick plates was considered.

Superhydrophobic-based corrosion mitigation systems and their effectiveness on dissimilar and similar friction stir spot-weld joint aerospace alloys

Next Materials
Traditional rivets have been a longstanding choice for securing aircraft components as permanent fasteners. A new technique called friction stir spot welding (FSSW) is gaining popularity as a rivet replacement.

Improved mechanical properties of cast Mg alloy welds via texture weakening by differential rotation refill friction stir spot welding [PDF]

, 2021
Cast magnesium alloys welds produced by refill friction stir spot welding (refill FSSW) show low lap shear strength (LSS) and constantly fail in stirred zone (SZ) shear mode. The cause is most probably related to the heavily textured microstructure. Here,

Numerical Investigation of the Influence of Welding Parameters on Quality of Laser Welded 304L Stainless Steel Sheets

Engineering Reports, Volume 7, Issue 6, June 2025.
This study investigates the influence of laser power and welding speed on the quality of 304L stainless steel laser welds using numerical and experimental approaches. Results indicate that optimal parameters (4 kW, 3 m/min) enhance penetration while minimizing the heat‐affected zone, providing insights for industrial laser welding optimization ...

Molluscan Shells, Spicules, and Gladii Are Evolutionarily Deeply Conserved

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 4, Page 198-213, June 2025.
Evolutionarily conserved transcription factor encoding genes and other genes are expressed in the epithelia that give rise to spicules (green) and/or shells (blue) in developmental stages of diverse mollusks, including polyplacophorans, aplacophorans, scaphopods, and cephalopods.

Multi‐year evaluation of rearing techniques for three sexually propagated Caribbean corals in a restoration setting

Restoration Ecology, Volume 33, Issue 4, May 2025.
In response to declining coral populations worldwide, conservation groups are increasingly applying restoration strategies to bolster abundance and diversity, including sexual propagation of corals. Collection and fertilization of coral gametes as well as larval rearing and settlement have been successful.
