Abstract

This work was focused on to study the changes in behavior of Magnesium alloy friction stir welded joint by inserted additional ‘SiC’ and ‘Al2O3’ Reinforced particles with an appropriate volume fraction at weld interface by providing gap provision and interlocking between two metal plates to form a metal matrix composite at weld interface which were enhanced the mechanical properties. Used a friction stir welding apparatus to stir reinforced particles into two base materials and a friction stir weld was formed. Moreover, metallurgical bonding was achieved between the reinforced particles and the base materials. Quality assessment included the visual inspection, temperature measurement in welding region, Tensile strength testing, impact strength testing, and hardness measurements. Research aimed at the recognition of FSW abilities to weld Magnesium alloys by inserting reinforced particles at weld interface and influence of reinforced particles and interlocking on weld properties. The research results have revealed that magnesium alloy AZ91 were weldable with reinforced particles using FSW process. Further it is concluded that Adding of reinforcement particles at weld interface increasing the mechanical properties such as hardness, yield strength, and small reduction in ultimate strength than base metal. But at the same time elongation decreases and the behavior of Material changes from ductile to brittle.
