چکیده
The current research is focused on the production of AW2024/B4C metal reinforced composite by using the liquid stir casting method. Ceramic particles armored composites are mainly used in engineering applications, which include aircraft, automotive, and marine fields. AW2024/B4C composites are produced by changing wt.% of B4Cp as 1.00%, 3.00% and 5.00%. The produced AW2024/B4C composites are machined as per ASTM E8-16a, IS1500, and IS7739 standard test size and subjected to artificial ageing. The hardness and tensile strength of AW2024/B4C composites were measured through a Brinell hardness tester and a universal testing machine, respectively. The microstructure of the prepared composite material was examined to determine the uniform distribution of reinforcement material. The highest hardness and tensile strength of AW2024/B4C composites were measured and found to be 84.97 BHN and 273.82 N/mm2 for AW2024/5%B4C with 5 hrs. ageing duration. The results achieved reveal that both hardness as well as tensile strength increased by increasing the weight percentage of B4C content. L9 standard orthogonal display was espoused to investigate the best parameter and also to authenticate the experimental test results. Further, a fracture study was done through SEM images to determine the mode of fracture.
