Abstract

In this work the Mechanical behavior of reinforced welded butt joints of AA6061 aluminium alloy fabricated by friction stir welding process has been investigated. 10%, 15%, 25%, 30% volume fraction of Aluminium Oxide (Al2O3) powder and Silicon carbide (SiC) particulates of 400 mesh were added at weld interface to enhance the mechanical properties at weld zone. This work has been focused to study the effect of Al2O3 and SiC as reinforcing material along with different volume proportions on the mechanical properties of friction stir welded joint of AA6061.The experimental results indicated that the reinforcing material and percentage of reinforcing material has a major effect on the mechanical properties of friction stir welded joint. The results of reinforced friction stir welded joints were correlated with mechanical properties of parent material and without reinforced friction stir welded joint. The best results have been obtained at 25% and 30% volume fraction reinforced particulates of Silicon Carbide and Aluminium Oxide respectively. But at the same time percentage of elongation decreases and the behavior of material changes from ductile to brittle.
