Analysis on mechanical properties of AA6061/Rice husk ash composites produced through stir casting technique

fabrication was done by stir casting techniques and the mechanical properties of AA6061/rice husk ash were assessed. The cast were produced with liquid metallurgy route through the reinforcement of 2–8 weight percentages of particle sizes of 75 mm rice husk ash. The microstructural test like SEM/EDS and mechanical properties were studied. From the results, the mechanical properties were found to increase at 8% rice husk ash reinforcement. SEM images revealed that homogenous dispersal of particulates without voids occur in cast and an increase up to 8% rice husk ash revealed substantial blending of matrix and reinforcement as evidenced in the microstructure examinatio
