Abstract:
The main purpose of this research is to investigate the influence of pin geometry on the microstructure and mechanical properties of the friction stir welded Al-Mg2Si metal matrix composite. Toward this end, friction stir welding (FSW) conducted using six geometrically different pin tools. Other welding parameters were remained unchanged. Microstructural evaluation using optical microscopy (OM) and scanning electron microscopy (SEM) revealed fragmentation of Mg2Si particles and Mg2Si needles existing in eutectic structure in stir zone and also the result showed a banded structure consisting of particle-rich and particle-free regions in stir zone of sample welded by triangular pin. The most uniform particle distribution was found in the case of using threaded tapered pin tool. Longitudinal tensile specimens were machined from the FSW samples parallel to the welding direction, respectively. The highest ultimate tensile strength (UTS) was recorded for the specimen FSWed with threaded and tapered with triangle pin tool. Fracture surface of tensile specimens were also studied employing SEM technique
