Abstract
Friction stir processing (FS) is an unique surface modification technique and modifying the microstructures of the metallic materials through thermomechanical processing. In the present work, effect of FSP process parameters like tool rotational speed and tool travel speed on the microstructure of the Al 5083 aluminium alloy was investigated. The results revealed that FSP has significantly refined the grain structure of the Al 5083 alloy. Ultrarefined grains were resulted in 1000 rpm tool rotational speed due to high heat input and subsequent rapid solidification. Grain refinement increases microhardness of the FSP samples. Higher microhardness observed at nugget zones due to ultragrain refinement in that zones.
