The vortex technique was used in this investigation to create A356.2 Al/Rice husk ash (RHA)
metal matrix composites (MMCs). The composites were made using various weight percentages
of reinforcement. Microstructural characterisation is done using a scanning electron microscope
with an energy dispersive X-ray analyzer. Properties such as ultimate tensile strength, density,
and hardness were examined. The microhardness findings showed that the matrix material near
the rice husk ash particle had a greater hardness. Particles of rice husk ash are added to
composites to increase certain of their mechanical qualities while decreasing their density.
