Abstract: The aim of this work is to demonstrate the feasibility of friction stir welding (FSW) for joining the Al-TiC composite. In this regard, the composite was manufactured by the accumulative roll bonding (ARB) process after 10 cycles and subsequently joined by FSW at a tool rotational speed of 560 rpm and welding speeds of 100 and 160 mm / min. The microstructural evolutions in the stir zone of the welded samples were investigated by scanning electron microscopy (SEM). It was revealed that in the stir zone of the sample by welding speed 100mm / min, TiC particles were uniformly imbedded in aluminum matrix and had a smaller average size after FSW, but the stiffness strength decreased due to grain growth caused by the frictional heat of tool rotation .
