摘要

Al-6061 is a lightweight metal alloy with good strength and corrosionresistance. It is widely used in the aerospace, automobile, and biomedical indus-tries. However, its mechanical properties can be further enhanced by reinforcing it with other materials. In this study, a hybrid metal matrix composite (MMC) was fabricated by reinforcing aluminium 6061 with silicon carbide (SiC) and an-imal bones powder (ABP). The MMC was fabricated using the stir casting meth-od, the mechanical properties of the MMCs were evaluated by tensile, hardness, and impact tests. The experimental results demonstrated significant improvements in hardness and tensile strength i.e. 17.1% and 32.1% over base alloy, while 10.7% decrement in impact strength with increasing reinforcement content. This paper concludes that SiC and ABP particles significantly enhanced the mechanical properties of aluminium 6061, offering potential applications in a different kind of industries, including automotive, aerospace, and biomedical.
