Friction stir processing (FSP) has been being used for composite fabrication for a couple of decades. Nano size composites have been fabricated by this technique. As the principle of FSP is similar to friction stir welding (FSW), likewise process parameters and their levels play a vital role in defect free stirred zone for the fabricated composites. Values of the process parameters affect the formation of defect free zone and the properties of the fabricated composites. Different materials require different values of these parameters. Researchers have optimised these parameters for different materials and the alloys of the single metal. As the hardness and metallurgical properties of the material change, the range of these process variables gets varied considerably. Present study consists of identification of the working range of the parameters viz. tool rotation, tool feed, axial thrust, number of FSP passes and the cooling condition to provide a gateway for the optimisation of these factors for pure Mg based TiC reinforced surface composites. Working range of tool rotation was found to be 500-700 rpm, tool feed to be 10-20 mm/min, axial thrust in terms of plunge depth to be 0.25 mm to 0.35 mm, 3 passes of FSP tool and the cooling condition to be under surface cooling (USC) at -10o C.
