Abstract
In present day Metal matrix composites (MMCs) are widely used in automotive and aeronautical domains due their superior mechanical properties compared to base metal. The current study evaluates the potentiality of conventionally prepared bamboo char particulates along with commercial grade B 4 C particulates as micro fillers dispersed into the Aluminium 6061 matrix. Three different compositions are fabricated through mechanical stir casting. Density measurements, tensile tests and Brinell hardness tests were carried out along with SEM fractographical analyses. It has been observed that addition of B 4 C and bamboo char led to an increase the hardness and tensile properties of aluminium 6061. But higher content of B 4 C caused a quasi-brittle mode of fracture.
