Abstract
Friction Stir Welding (FSW) of metal matrix composite (MMC) provides the grain refinement and reinforcement redistribution of the composite used for wide application in aerospace and structural. This wide application needs development of best-suited joining process for MMC which is complicated to unite by the traditional welding process. The paper observed the consequence of the welding parameter and tools’ geometry on the mechanical properties of the friction stir butt welded in-situ RZ5-10wt%TiC composite. The flame-hardened tool steel is utilized as a material for the tool. The welding has done using different welding speed (931, 1216 mm/min), Tool speed (30, 40 rpm) and shoulder diameter of the tool (17, 19 and 21 mm). The grain refinement of the RZ5-10wt%TiC composite and matrix alloy observed in weld stir zone. It is due to grain size decrease in RZ5-10wt%TiC composite. The microstructural investigations have been analyzed by means of scanning electron microscope. The hardness test has done on Vickers hardness tester showed fairly increased in mean hardness of the welded composites according to the designated parameters. The UTS of the welded composite is increased in comparison to RZ5-10wt%TiC composite. The predictive model has also been developed based on the full factorial design to evaluate the welding parameters. Further, the multi-response technique was utilized to optimize the welding parameters. The observed 0.39% error revealed the competence of the model in the optimality test.
