IJRET: International Journal of Research in Engineering and Technology eISSN: 2319-1163 | pISSN: 2321-7308 INFLUENCE OF VOLUME FRACTION, SIZE, CRACKING, CLUSTERING OF PARTICULATES AND POROSITY ON THE STRENGTH AND STIFFNESS OF 6063/SICP METAL MATRIX COMPOSITES A. Chennakesava Reddy1 1Professor, Department of Mechanical Engineering, JNTUH College of Engineering, Kukatpally, Hyderabad – 500 085, Telangana, India Abstract The objective of this study is to examine the influence of volume fraction, size of particulates, formation of precipitates at the matrix/particle interface, particle cracking, voids/porosity, and clustering of particulates on the strength and stiffness of 6063/SiCp metal matrix composites. Tensile strength and stiffness increase with an increase in the volume fraction of SiC particulates. The tensile strength and stiffness decrease with increase in size of the particulates, presence of porosity, clustering, and particle cracking. Formation of particulate clusters is more prominent in the composites having very small-reinforced particulates. Mg2Si compound is likely to precipitate at the matrix/particle interfaces of 6063/SiC composite.

INTRODUCTION matrix composite have become of principal importance for the manufacturer to make a quality product as per the Consolidation of a high strength ceramic particulate in a soft designer specifications. The objective of this work is to metal matrix is the technological renovation in the domain study the influence of the volume fraction and particle size of composites for the designer to assure high specific elastic of SiCp, clustering and cracking of particulates, modulus, strength-to-weight ratio, fatigue durability, and voids/porosity, and formation of precipitates at the wear resistance in the fields of aerospace and automotive particle/matrix interface on the tensile strength and stiffness applications.
