【 摘 要 】

Because of its exceptional qualities, aluminium composites are frequently employed in aircraft applications. Aluminium alumina composite was manufactured in-situ using the AA-6061 T6 matrix alloy and 3 %age, 6 %age (Nichrome) powder. Optical metallography, Image Analysis, and micro hardness tests were used to assess the in-situ composites. The specimens then liquid preheated at 550 °C for 3 hours and then aged at 180 °C for 7 hours to improve the durability in mechanical characteristics. In comparison to the as cast samples, the heat-treated samples showed significantly higher mechanical properties. AA-6061 T6 matrix composite reinforced with in-situ alumina particle with TiC was also studied for grain refining. The Al-4.5 % Ti-1.5 % C master alloy has been shown to be an effective grain refiner.
