TL;DR: In this paper, the microstructural and mechanical properties of the friction stir welding (FSW) of 1060 aluminum alloy to a commercially pure copper were investigated. And the effect of formation of hard and brittle intermetallic phase at the interface of the joints on the shear strength of the joint was discussed.

TL;DR: In this paper, the effect of welding speed on interface morphology, microstructure, and joint strength was investigated for lap joints of 1060 aluminum alloy and commercially pure copper was produced by friction stir welding, and the results revealed that in the aluminum close to the Al/Cu interface, a dark area was formed.

TL;DR: In this paper, the effect of the welding speed on the microstructure and mechanical properties of the stir zone (SZ) in friction stir welding (FSW) of SAF 2205 duplex stainless steel was investigated.

TL;DR: In this paper, a debonding failure mode in the Al/Mg dissimilar weld nugget was investigated by SEM and surface fracture studies indicated that the presence of intermetallic compounds in the weld zone controlled the failure mode.

TL;DR: In this article, solid-state friction stir welding with different tool rotation and welding speeds was used to obtain a quality joining of steels to aluminum alloys by fusion welding processes due to the large difference between melting temperatures and the formation of brittle Al/Fe intermetallic compounds at the joint interface.
