In this study, hybrid nanocomposite powders based on Al2024, reinforced with nano-sized B4C and graphite particles, were produced using the mechanical milling method. Our research focused on examining the effect of nano-sized B4C content on the properties of Al2024/Graphite/B4C hybrid nanocomposite powders. These properties include the morphology, particle size and distribution, and microhardness of individual particles. To investigate the effect of nano-B4C reinforcement, we varied the B4C content at 0.25, 0.5, 0.75, and 1 wt%, while keeping the graphite content constant at 0.5 wt%. Scanning Electron Microscopy (SEM) at different magnifications was employed to examine the powder morphology in detail. Additionally, an advanced computer-aided laser particle size analyzer was used to determine particle size and distribution within the powders. The microhardness of the powders was evaluated using a multifunctional digital hardness tester. Significant changes in powder morphology were observed with increasing nano-B4C reinforcement content, as the powders tended to acquire a more spherical structure. Interestingly, while the distribution of particle sizes remained relatively stable with increased B4C content, a gradual decrease in average particle size was observed. A notable increase in particle microhardness was also recorded with higher B4C content.
