Fabrication and Characterization of A356.2-Rice Husk Ash Composite using Stir casting technique

摘要

Fabrication and characterization of A356.2 alloy reinforced with rice husk ash (RHA) particles are dealt in the present study. The metal matrix composites (MMCs) were prepared by addition of 2, 4 and 8 wt% RHA particulates through stir casting technique. Scanning electron microscope equipped with energy dispersive X-ray analyzer is used for micro structural characterization and the presence of silicon particles in the composites. Mechanical properties like density and hardness were measured for the composites. As the percentage of RHA particles increases, the density of the composites decreases and there is slight increase in the hardness were observed.
