Abstract: The proceedings of this presentations enables us to explore the effect of B4C and h-BN particles on Aluminum based metal matrix composites (AL MMCS).The composites were fabricated with different reinforcement percentages of h-BN and B4C in aluminum using powder metallurgy technique. To obtain homogenous mixture between the powders, for small duration of milling, attrition mill is adopted. The powders were then compacted to optimal compaction pressure and sintered under nitrogen atmosphere. The prepared composites were polished and etched for micro structural analysis. Also determine the Brinell’s and Vicker’s hardness numbers. Results reveal that there is good improvement of results in composites than base metal.
