Abstract

Aluminum Matrix Composites (AMCs) allude to the sort of light weight elite aluminum driven material matrix. AMCs comprise of a non-metallic reinforcement which included into aluminum grid which offers worthwhile properties over base material. Reinforcements like Sic, CSAp, B4C, Al2O3, TiC, TiB2, TiO2 are typically liked to enhance the mechanical properties. Here aluminum LM25 is chosen as framework material, while coconut shell powder is chosen as support (reinforcement) material. Coconut shell powder is included 2%, 4% and 6% of weight to LM25 alloy to manufacture the MMC. The creation of Aluminum MMC is finished by Stir casting strategy. Stir casting is a fluid state technique for composite materials manufacture, in which a scattered stage is blended with a liquid framework metal by methods for mixing. The created tests were tried for mechanical properties. Promote the specimens are heat treated (solution for 500°C for 5 hrs, quenching on water and ageing for 170°C for 3 hrs). These specimens again tested for mechanical properties (hardness and tensile) and compared with untreated composites. The microstructure indicates genuinely homogeneous distribution of CSAp in the matrix.

Keywords:LM25 composite, Metal matrix composite, Mechanical properties, Tribology properties, Stir casting.
