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.
