초록
The present study elucidates the influence of reinforcement particles in friction stir welded aluminium (Al 6063) matrixcomposites on mechanical properties of the metal matrix composition. Initially composites were successfully fabricated withdifferent weight percentage and combination of reinforcements (graphite (gr), B4C and SiC) through stir casting technique. All sets of composite specimen were welded through solid state joining process of friction stir welding technique, theparameters such as tool rotational speed (800, 1000 and 1200 rpm), welding speed (20 and 40 mm/min) and axial loading (10and 20 kN) are taken for characterization of fabricated composites. The effects of friction stir welding parameters wereexamined by mechanical and microstructural characterizations. The composites microstructure and dispersion of particlereinforcements were analysed through optical microscope and also the mechanical properties of yield strength, ultimatestrength and elongation were analysed using universal testing machine. The optimized friction stir weld parameters wereidentified for 20% weight fraction reinforced hybrid composites.
