The friction stir welding process has been used to join 13mm gauge 2024-T351 aluminium alloy plates together. A detailed microstructural study of the resulting weld was carried out using Differential Scanning Calorimetry (DSC), hardness testing, Scanning Electron Microscopy (SEM) and Electron Backscatter Diffraction (EBSD). DSC was used to explain the hardness results at a number of regions acr...

Friction stir welding (FSW) adalah suatu teknologi pengelasan yang merupakan proses solid-state joining bisa digunakan untuk menyambungkan material aluminium dengan mampu las rendah. Proses FSW memanfaatkan putaran dari tool menggesek dua buah lempengan logam akan disambung. Aluminium 2024 T3 ketebalan 4 mm disambung menggunakan variasi feedrate 13 mm/menit, 15 dan 25 kecepatan spindle 910 rpm ...

In this paper we utilize Support Vector Machines to predict the degradation of the mechanical properties, due to surface corrosion, of the Al 2024-T3 aluminum alloy used in the aircraft industry. Precorroded surfaces from Al 2024-T3 tensile specimens for various exposure times to EXCO solution were scanned and analyzed using image processing techniques. The generated pitting morphology and indi...
