Fracture Surface Analysis of EN AW 5754 Aluminium Alloy during Submerged Friction Stir Processing

Article Preview

Abstract:

The study examines the effects of the Friction Stir Processing (FSP) process on the EN AW 5754 aluminium alloy, conducted under underwater conditions. FSP is an innovative technology used to improve the mechanical properties of materials through plastic deformation. Fracture surface analysis is essential for understanding how the process influences the internal structure of the alloy and its behaviour during fracture. The results obtained from the fracture analysis provide insights into the deformation mechanisms and how processing conditions affect the material's structural integrity. This study contributes to the development of aluminium alloys with enhanced properties, with applications in fields such as the automotive and aerospace industries.
