Abstract

Friction stir welding could be a solid-state welding has a wide range of applications in industries like aerospace and automobile industries. In this work, the friction stir weld ability of aluminium metal matrix composite(AMMC) using H13 tool and sensitivity of parameters like tool rotation speed, traverse speed and axial force are assessed on final durability, hardness and microstructure. It was observed that the tensile strength and hardness are increased by increasing the tool rotation speed. The microstructure showed fine Al-Mg-Si eutectic particles in a matrix of Al solid solution.
