Abstract:

This research focuses on the detailed analysis of fracture surfaces in aluminium alloy EN AW 1200, processed through underwater friction stir processing. The material was subjected to multiple processing passes, and tensile failure specimens were subsequently extracted for further analysis. Microscopic evaluation of the fracture surfaces was conducted using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). These advanced techniques were employed to examine the microstructure, fracture morphology and elemental composition of the processed material. Insights gained from the analysis of the fracture surfaces of aluminium alloy EN AW 6082, similarly processed through underwater friction stir processing, provide significant findings. These insights can guide improvements in both the quality and reliability of the aluminium alloy in question. The findings from this study contribute to the existing body of knowledge on underwater friction processing, offering important information related to the mechanical performance of aluminium alloy EN AW 1200.
