Abstract: In the current work, attempts were made to create friction stir processed Al-based nano composites (FSP). The microstructure of the nugget zone (NZ) was improved by the addition of Al2O3 and Tic nanoparticles, and the growth of granular material in the heat-affected zone was constrained (HAZ). The impacts of adding Al2O3 and Tic nanoparticles on the development of the grain structure and various mechanical properties of the friction stir-welded aluminium matrix were thoroughly investigated. The results showed that the addition of Al2O3 and TiB2 nanoparticles caused a remarkable refinement of grains in the nugget zone because of the pinning effect produced by nano-sized Al2O3 and TiB2 particles that prevent the grain growth followed by recrystallization during FSW, leading to a remarkable reduction in the amount of grain that was unable to be refined.
