ABSTRACT. The hybrid metal matrix composites (HMMCs) has been widely used due to its improved properties with low porous and low density in many engineering application. In the present work, influence of hybrid reinforcements on mechanical characteristics of hybrid metal matrix composites synthesised by stir casting process have been studied. The hybrid metal matrix composites (HMMCs) are synthesised by amalgamate the flyash particles with synthetic ceramic particles ie, SiCp and Al2O3 into the vortex of matrix alloy with an equal proportion of 3 wt.%, 6 wt.% and 9 wt.%. The present investigation results inferred that the UTS, hardness and porosity of a material increased with the increase of hybrid reinforcement content, whereas the density decreases. In addition, the SEM analysis was employed to examine the microstructural characterization of hybrid composite and the results signify that the hybrid reinforcement particles are dispersed uniformly in the matrix material and the porosity percent has found to be in acceptable range for the cast hybrid composites.
Keywords: hybrid metal matrix composites, flyash, synthetic reinforcements, mechanical and physical characteristics, stir casting process.
