In the present investigation, Al2024 alloy reinforced with boron carbide particulates with three different mesh size (100, 200 and 300) have been chosen for the preparation of MMCs. Stir casting route was adopted by varying weight percentage of boron carbide particulates by 1 wt.%, 3 wt.% and 5 wt.%. The cast component was machined through conventional lathe machine tool as per ASTM E8-16a size for tensile test specimen. The tensile test specimens have been subjected to solutionzing treatment at 520 for24 hours followed by water quenching. The quenched test specimens are then subjected to artificial ageing at 175 for holding duration of 1 hr., 3 hrs. and 5 hrs. The tensile specimens after artificial ageing were tested using UTM to evaluate the ductility and yield strength of the formed composite material. It is noticed that ductility found to be decreased with increase in wt.% of boron carbide in the Al2024 alloy, whereas yield strength was found to be improved. Taguchi Technique was adopted to evaluate the S/N ratio, optimization, influence of process parameter and regression equation were derived for the confirmation of experimental results through Minitab software. SEM images reveal the uniform distribution of boron carbide in Al2024 alloy. Ductile tearing was observed in pure Al2024 alloy and the formed composite material.

在目前的研究中，选择了三种不同目数（100、200 和 300）的碳化硼颗粒增强的 Al2024 合金来制备 MMC。采用搅拌铸造路线，碳化硼颗粒的重量百分比变化 1 wt.%、3 wt.% 和 5 wt.%。铸件通过常规车床机床按照 ASTM E8-16a 尺寸进行机械加工，用于拉伸试样。拉伸试样已在 520℃ 下进行 24 小时固溶处理，然后进行水淬。然后将淬火的试样在175℃进行人工时效，保持时间为1小时、3小时。和 5 小时。人工时效后的拉伸试样采用 UTM 进行测试，以评估成型复合材料的延展性和屈服强度。值得注意的是，随着 Al2024 合金中碳化硼重量百分比的增加，延展性降低，而屈服强度提高。采用田口技术对信噪比进行评估，通过Minitab软件推导出工艺参数的优化、影响和回归方程，对实验结果进行验证。SEM 图像揭示了 Al2024 合金中碳化硼的均匀分布。在纯Al2024合金和形成的复合材料中观察到延性撕裂。SEM 图像揭示了 Al2024 合金中碳化硼的均匀分布。在纯Al2024合金和形成的复合材料中观察到延性撕裂。SEM 图像揭示了 Al2024 合金中碳化硼的均匀分布。在纯Al2024合金和形成的复合材料中观察到延性撕裂。
