Abstract
Abstract The present study was aimed at evaluating the hardness and ductility of boron carbide and short E-glass of AA 2014 composites. These AMCs with individual and multiple reinforcement (hybrideMMCs) are finding increased applications in aerospacertechnology, automobileg, space, underwater and transportationiapplications. An effort is made to enhance hardness & ductility of AMCs by reinforcing AA 2024 matrix with varying proportion of both B4C and Short E-glass fiber by stir casting method. Aluminum alloy matrix varying proportions of boron carbide particulates and Short E-glass fibers were fabricated. The hardness and ductility of the fabricated AMCs were analyzed. After obtaining results the taguchi analysis (MINITAB17) is done for input response such as composition, stirring speed and, stirring temperature by selecting the L16 orthogonal array to study the effect of each process parameter for hybrid composite material. Based on the results obtained from hardness test of the metal matrix composites it is observed that, the hardness increases as the increase in the amount both B4C of short E-glass but ductility of hybrid composite material decreases.
