Engineering Reports, Volume 6, Issue 12, December 2024.The graphical abstract demonstrates that adding 9 wt% nickel to an Al‐Si matrix composite increases hardness by 25.93%, tensile strength by 40.3%, and density by 6.01%, but decreases impact strength by 50% compared to the A413 alloy. It includes SEM images, a stir casting schematic, and data on tensile and impact behavior.
