This paper presents an analysis of the fracture surface of the EN AW 7075 aluminum alloy, processed through submerged friction stir processing in water. Multiple passes were used during processing. Specimens prepared from the processed material were also examined with a focus on their fracture surfaces in relation to tensile failure. The investigation of these surfaces included microscopic analyses using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) techniques to examine the microstructure, fracture surfaces, and elemental composition of the analyzed area. Insights from the analysis of the fracture surface of the EN AW 7075 aluminum alloy processed by submerged friction stir processing in water provide a basis for recommendations to enhance the alloy's quality and reliability. The findings of this research advance knowledge on submerged friction stir processing in water for the EN AW 7075 aluminum alloy.

This paper provides an analysis of the fracture surface of aluminum alloy EN AW 6082 Submerged Friction Stir Processed. Processing was performed in multiple passes. The specimens taken from the material processed for the tensile failure test were also analyzed from the point of view of the failure surfaces. The investigation of these surfaces involved microscopic analyzes carried out with the help of scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) techniques, to study the microstructure, fracture surfaces and constituent elements of the analyzed area. Based on the conclusions obtained from the analysis of the fracture surface of the aluminum alloy EN AW 6082 Submerged Friction Stir Processed, recommendations can be made to improve the quality and reliability of the alloy. The results of this research contribute to the development of knowledge on Submerged Friction Stir Processed of aluminum alloy EN AW 6082.
