Weldability and mechanical properties of AA5083-H112 aluminum alloy and pure copper dissimilar friction spot extrusion welding-brazing

M. Paidar et al.

Summary: The friction spot extrusion welding-brazing (FSEW-B) process was used to join AA5083-H112 aluminum alloy and pure Cu with the help of a Zn interlayer to improve mechanical properties of the dissimilar joint. The data showed that FSEW-B eliminated keyhole defects and reduced brittle intermetallic compounds (IMCs) at the Cu/Al interface, resulting in improved strength and ductility of the weld sample.

Modified friction stir clinching of AA6061-T6/AA5754-O joint: Effect of tool rotational speed and solution heat treatment on mechanical, microstructure, and fracture behaviors

M. Paidar et al.

Summary: The mechanical properties of the improved heat-treated AA6061-T6/AA5754-O aluminum joints were enhanced by adjusting the tool rotational speed and applying a heat treatment process, which successfully reduced unbonded regions and increased the load-bearing capacity of the joints.

Friction spot extrusion welding-brazing of copper to aluminum alloy

M. Paidar et al.

Summary: Changing the shoulder geometry in friction spot extrusion welding-brazing can increase the tensile/shear strength of the joint, attributed to the larger brazed zone and complete filling of the pre-threaded hole.

Dieless Friction Stir Extrusion-Brazing (DFSE-B) of AA2024-T3 aluminum alloy to Copper with Zn interlayer

M. Paidar et al.

Summary: The study demonstrated the improved load-bearing performance of dissimilar AA2024-T3/copper joint using Dieless Friction Stir Extrusion-Brazing (DFSE-B), compared with Friction Stir Spot Welding-Brazing (FSSW-B). The DFSE-B process suppresses flow-induced defects, resulting in enhanced tensile-shear load and toughness due to the absence of tool-induced keyhole and mechanical interlocking of softer Al alloy into harder Cu alloy. DFSE-B proves to be a suitable welding alternative for reactive metals.

Diffusion brazing of 321 stainless steel to IN738 using 54Ag-40Cu-5.0Zn-1.0Ni powder-mixture interlayer

M. Paidar et al.

Summary: The application of a 54Ag-40Cu-5.0Zn-1.0Ni powder-mixture interlayer in the diffusion-brazing of Inconel 738 and AISI 321 stainless steel, coupled with an increase in holding pressure, facilitates better atomic diffusion, formation of uniform reaction layers, and enhanced shear strength of the brazed joints.
