The present study discusses the effectiveness of stir casting technique using the mixed salt route method and the joining of obtained in-situ TiB2/Al-Si composites using friction stir butt welding technique. The bimetallic flame-hardened friction stir welding tool with a threaded titanium probe having different shoulder geometries was used for the study. The variation in process parameters; tool shoulder geometry, tool rotational speed, and welding speed significantly affects the properties like ultimate tensile strength, elongation, and micro-hardness of the welds. The change in the grain morphology along with refinement and uniform redistribution of the reinforcement phase was observed with the Titanium weld probe through all the experiments. Microstructural studies were conducted using scanning electron microscopy, high-resolution electron microscopy, and X-Ray diffraction. A statistical model and optimization techniques were used to evaluate the output responses of the joints. A substantial improvement in the joint properties was observed in comparison with base composite.
