“…The tribological studies showed that surface composite has the highest wear resistance and hardness [26]. [27] fabricated metal matrix composite via FSP and reported the more homogeneous dispersion of particles and fine equiaxed grains in the stir zone and improved hardness up to 55 % and wear rate of composite has reduced to 9.7%. J. Gandra et al [28] fabricated the AA5083/Sic AMC using FSP and studied the effect of groove offset on the distribution of ceramic particles.…”

Friction stir processing (FSP) is solid state novel technique developed to refine microstructure and to improve the mechanical properties and be used to fabricate the aluminium alloy matrix composites. An attempt is made to fabricate AA6061/TiB2 aluminium alloy composite (AMCs) and the influence of process parameters like rotational speed, transverse feed, axial load and percentage reinforcement on microstructure and mechanical properties were studied. The microstructural observations are carried out and revealed that the reinforcement particles (TiB2) were uniformly dispersed in the nugget zone. The Tensile strength and Hardness of composites were evaluated. It was observed that tensile strength, and hardness were increased with increased the rotational speed and percentage reinforcement of particles. The process parameters were optimized using Taguchi analysis (Single Variable) and Grey analysis (Multi Variable). The most influential parameter was rotational speed in single variable method and multi variable optimization method. The ANOVA also done to know the percentage contribution of each parameter

“…They reported that the maximum ultimate tensile of composite was improved about two times compared with as-received aluminium. Dolatkhah et al (2012) produced metal matrix composite on surface of 5052 aluminium sheets by means of 5-μm and 50-nm SiC particles using FSP. They noticed that hardness value of fabricated composite was improved up to 55% and wear rate was reduced about 9.7 times comparing with as-received 5052 aluminium.…”

Abstract. Aluminium metal matrix composites finds its application in aerospace, automobile, and energy industry owing to their excellent mechanical properties such as low density high strength, light weight, high strength-to-weight ratio and fatigue and corrosion resistances. Further the addition of nano size particles improves mechanical properties of the composites. The present work is focused on the mechanical performances of aluminium SiC nano composites. Instead of making bulk composites, the surface layers on the substrate improve the mechanical properties. For the fabrication of such surface composite layer, the new modification technique, friction stir processing (FSP) is used. FSP technique is used to produce defect-free surface composite with a good bonding and uniform distribution of reinforcement particles within an aluminium matrix. Various process parameters such as rotational speed, transverse feed, and volume fraction of nano SiC, on mechanical properties is investigated. The mechanical properties such as micro hardness and flexural strength were measured using micro hardness tester and universal tensile testing machine respectively.. In addition to that the morphology of the specimen is examined through scanning electron microscope to study them in detail. . IntroductionIn the modern era, a material with high strength is a basic requirement for various engineering applications. In order to satisfy these needs, composite materials have found a wide range of applications in various industrial components and structures because of their improved mechanical properties. Among various types of composites materials available, metal matrix composites plays a vital role in terms of high strength or stiffness, low density, good corrosion as well as fatigue resistance. For further improving the mechanical properties of such composites, the widely practiced method is the incorporation of either micron/Nano-sized inorganic particle in the metal matrix. Most of the properties improvement by incorporation of such nano particles in aluminium metal matrix composites fabricated by friction stir processing route is not fully explored yet.
