Abstract: In this study, the effect of tool pin geometry on the microstructure and mechanical properties friction stir processed (FSP) specimens of ZE41 magnesium alloy were investigated. The four different tool pin profiles such as triangular, square, taper cylindrical and threaded taper cylindrical with process parameters of 1120 RPM, 25mm/min and tool tilt angle 10 were considered. Microstructures of the processed specimens are examined using scanning electron microscope (SEM) and the wear behavior was observed using pin on disk tribometer. The consequences show that the triangular tool pin produced defect free joints, finest microstructure, higher mechanical and wear properties.
