“…Currently, FSW allows for the incorporation of various materials in the production of weldments, enabling the creation of both similar and dissimilar joints within single structures. Extensive research has been conducted to investigate the effects of FSW on different materials and their properties, focusing on extracting samples from diverse orientations such as traverse, longitudinal, and diagonal [10][11][12][13][14][15][16][17]. Furthermore, samples have been collected from different locations along the joint line, including the start, middle, and end sections, to comprehensively examine their properties [18][19][20][21][22].…”

This study investigates the mechanical and microscopic characteristics of the friction stir welded AA5083/AA6082 dissimilar joint. The welding process was performed at a rotational speed of 900 rpm, traverse speed of 60 mm/min, and a tool tilt angle of 1º. Samples were extracted from the joint's start, middle, and end positions in both the traverse and longitudinal directions. The analysis of these samples involved various tests, including microstructural analysis, bending, and tensile tests. The microstructural analysis revealed non-linear behaviour in both the longitudinal and traverse sampling directions along the joint. Specifically, there were notable differences in the microstructure between the different locations within the joint. In terms of mechanical properties, the ultimate tensile strength results of the traverse specimens were found to be higher compared to the specimens sampled longitudinally. This suggests that the joint's strength may vary depending on the sampling direction. On the other hand, the flexural strength results showed a contrasting pattern, with the traverse specimens exhibiting lower strength values compared to the longitudinally sampled specimens. This indicates that the joint's resistance to bending forces may differ based on the sampling direction.

AMg61 (Al-6.2% Mg), a novel form of high-strength, high-magnesium-content aluminum alloy, has been developed for specific maritime engineering in recent years, while its corrosion behavior in seawater is still unknown. Therefore, the corrosion behavior of AMg61 in the simulated seawater was investigated herein, using a weight-loss test and different electrochemical measurements. In addition, corrosion morphology and chemical contents were characterized by metallography, scanning electron microscopy, and energydispersive spectroscopy. The results demonstrated that intergranular corrosion and microcracks developed first in the second phase of AMg61, followed by pitting corrosion. The matrix of AMg61, on the other hand, exhibited a uniform and exfoliation corrosion. The corrosion rate gradually decreased over time.
