Popis: Metal Matrix Composites (MMC's) have created a better interest in recent times for various applications. Advance composite materials like AlSiC metal matrix composite is gradually becoming very important materials manufactu ring aerospace, satellite, automotive and automobile Indus tries due to their superior properties such as light weight, low density, high strength to weight ratio,hardness, temperature withstand and thermal shock resistance, superior wear and corrosive resistance, high specific modulus, highfatigue strength etc. In this paper, aluminium Al-6063&SiC are produced reinforced particles metal matrix composites using manual stir casting technique. In the prepared MMCs flats and round cross section rods are prepared with varying reinforced particles bychanging the weight fraction ranging from 5%, 10%, 15%, and 20%of SiC. The stirring process is carried out manually by a graphite stirrer. The prepared specimens are further tested using a On line monitoring technique namely, Acoustic Emission. Further the same specimens were tested in to various conventional mechanical testing via. Impact strength, microstructure test and micro hardnesstest, Finally it is clearly viewed that hardness of the specimen might be increased with an increase of weight fraction of SiC particle. Also it is observed that the tensile strength and impact strength propertiesare increased with addition of weight fraction of SiC reinforced particle. Similarly by varying the particle size and weight fraction of SiC more other mechanical test can be attempted.
