An Experimental Investigation of Friction Stir Process Al6082 T6 51

Abstract


Friction stir processing (FSP) is emerging as a promising tool for micro structural modification. The current study assesses the effects of FSP on the microstructure and mechanical properties of an Aluminium alloy. FSP eliminates porosity and significantly refines the grain structure. The extent of particle refinement varied with changes in tool pin profile. In this study TiC and SiC are mixed in the welded zone using different tool pin profiles with constant welding parameters. Hardness value of the processed material changed significantly as a result of FSP and it was found that hardness varies with different pin profile was maximum with pentagonal tool pin profile. Furthermore, it was found that recrystallisation was better with pentagonal tool pin profile.

Keywords
