Effect of Mechanical Properties on Rice Husk Ash Reinforced Aluminum alloy (AlSi10Mg) Matrix Composites.

摘要

The application spectrum of low cost material reinforced metal matrix composites is growing rapidly in various engineering fields. In this way, present study indicates the possibilities of reinforcing aluminium alloy (AlSilOMg) with locally available inexpensive rice husk ash for developing a new material. A rice husk ash particle of 3, 6, 9 & 12 % by weight were used to develop metal matrix composites using a liquid metallurgy route. The surface morphology was studied using scanning electron microscope for analyze the distribution of RHA particles. The mechanical properties such as tensile strength, compressive strength, hardness and percentage elongations are studied for reinforced RHA composites. The results reveal that the percentage reinforcement of RHA will increase ultimate tensile strength, compressive strength and harness of the composite.
