Abstract: In recent years Al2024 alloy had increasing applications in all the areas due to its good formability, excellent properties and etc. By using nano size B4C as size and graphite as reinforcements the fabrication process are done by Powder metallurgy process with overall 12 compositions primary and secondary specimens. Nano B4C are used as reinforcements from 3-15% with step of 3% as primary specimen and with addition of graphite of 3% in every reinforcements same manufactured. All specimens are manufactured by powder metallurgy technique and had a wide application. Hardness values are taken and each specimen is subjected to aging process. In aging process are subjected to 495°C and soaking for 2 to 10 hours. The cooling process can done by in three medium water. In each case hardness values are taken with micro Vickers tests. All results are taken shows that increase in hardness with aging process. FESEM analysis is conducted to know the microstructure of composites.
