    Abstract :

    AA6063 has good surface finishing, high corrosion, and resistance, is readily suited to processing and can be easily anodized, has high strength to weight ratio but low hardness and wear resistance properties. Friction stir processing is a novel technique of changing the properties of a metal through intense, localized plastic deformation. Frictions stir processing used in casting, powder metallurgy and surface modification. In the present research, a metal matrix composite was fabricated by using AA6063 alloy as the base metal. Tungsten carbide particles with 5 ┬Ám particle size were added reinforcement. Tungsten carbide particles packed in series holes of diameter 2 mm and depth 3.5 mm. A single pass FSP was carried out using constant tool rotational speed of 1500 rpm and variable transverse speed of 30 mm/min, 40 mm/min and 50 mm/min. A tool made of high carbon high chromium steel, having a two different pin profiles cylindrical left hand threaded and square tool pin were used. Tool shoulder diameter and length of tool pin were 20 mm and 4 mm respectively. The side of square tool pin were 4 mm. The mechanical and metallurgical properties of composite material fabricated by FSP were investigated. The results were compared with the properties of base metal. The results depict that UTS, yield strength and micro hardness values of composite fabricated with cylindrical left hand threaded pin tool were higher as compared to square tool pin profile. With increase in transverse speed UTS, micro hardness and yield strength increases and optimum value was obtained at transverse speed of 50 mm/min. From microstructure evaluation, reinforced particles were uniformly dispersed with left hand threaded tool at transverse speed of 50 mm/min and fine grain size was obtained.
