Processing, microstructure and mechanical properties of nickel particles embedded aluminium matrix composite

▶ Al-Ni particle composite was successfully processed by FSP. ▶ No harmful intermetallics formed. ▶ The composite showed a 3 fold increase in yield strength with high ductility. ▶ FSP also lead to a refined recrystallized grain structure. ▶ A continuous type dynamic recrystallization process seems to be working during FSP.
