Description :
Owing to the enhanced mechanical properties of Friction stir (FS) welded alloys are more significant than the conventional welding process. The primary study was to investigate the influence of process parameters on the mechanical properties of FS welded metal matrix composite. In order to weld the composite a threaded profile pin tool (TPP) was used. In the nugget zone numerous small particles and the uniform distribution of refined grains were obtained and this was depicted by the microstructural characterization. The higher hardness was attained at the nugget zone compared to that of the base material. A joint efficiency of 89% was accomplished in transfer direction. The ductile fractures of the Al-Cu matrix and the brittle fracture of the reinforcement particles were disclosed on fracture surface of specimens. Keywords—Friction Stir welding, metal matrix composites, nugget zone
