| Abstract Scope |
The aim of this work is focused on investigating the effects of friction stir processing (FSP) on supersonic particle deposited (SPD) 316L stainless steel. Prior to FSP, the SPD samples were subjected to annealing at 1000 °C mitigating the residual stresses developed on the sprayed alloy. The FSP was performed with using molybdenum tool at rotational speeds of 800 and 1400 rpm. The effect of FSP was analyzed in terms of change in microstructure, mechanical and tribological properties. The FSP zone of both samples exhibited an equiaxed smaller grains due to dynamic recrystallization whereas the following affected layers showing more of a lamellar grain structure. The microstructure also confirms reduction in pores. These reductions in grain size and pores led to improvement in mechanical and tribological properties. The study also suggests that potential of FSP process to tailor the properties of additively manufactured metals and alloys. |
