    Experimental investigation of fabricated SiC reinforced aluminium based metal matrix composite
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-11) Rawat, Rohit; Singh, V.K.
    Aluminium has been widely used in engineering applications because it is light in weight. A vast number of experimental studies have been performed on addition of hard ceramic particles to aluminium matrix to enhance its strength, hardness and wear resistance. Every efforts aims to develop a material which can be appropriate for various industry and machinery purpose. In the present study, a modest attempt has been made to develop cast aluminium based silicon carbide particulate metal matrix composite. Here work objective is to develop a conventional low cost method of producing MMCs and to obtain homogeneous dispersion of ceramic particles. To achieve these objectives stir casting technique has been adopted. Adding Magnesium has improved wettability between aluminium and SiC particles by reducing the silicon di oxide layer on the surface of the SiC. In this work, we examine the influence of reinforcement on different mechanical and tribological properties. Density, porosity, microhardness, yield strength, ultimate tensile strength, percent elongation, and young modulus have been used to evaluate the mechanical properties. Pin on disc and dry sand abrasion tests were used to determine tribological characteristics. Microscopy tests, SEM show the dispersion of reinforcing phase in the matrix phase. In the case of SiC, mechanical and tribological properties are optimum at 21 wt. % of SiC.
