This article deals with the armour grade AA7075-T651 metal matrix nanocomposite reinforced with SiC and Al2O3 nano particles produced by stir casting method. The produced nanocomposite rods are joined without any external source by friction welding process to understand its fatigue and tensile behaviors of its fully deformed zone. The experiments were conducted by using rotating beam fatigue testing machine at different stress levels and the joints characterization were analyzed with various advanced testing machines. The relationship between tensile and fatigue properties of joints were established. Finally, the characteristics of friction welded joint was investigated with the help of scanning electron microscope, optical microscopy analysis under optimized condition.
