In this study, nanocrystalline Al–Ni intermetallic compounds were synthesized by mechanical alloying (MA) of elemental powders, focusing on the effects of varying milling times. Using a ball-to-powder weight ratio of 10:1 and a rotation speed of 350 rpm, the phase evolution and microstructural changes of the powders were investigated through x-ray diffraction (XRD), scanning electron microscopy, and energy-dispersive x-ray spectroscopy. The analysis employed the Williamson–Hall formula to estimate crystallite sizes based on the broadening of XRD peaks. The results indicated that an optimal MA time of 12 h successfully led to the formation of an Al–Ni intermetallic phase exhibiting a crystallite size of less than 40 nm. These findings contribute to the understanding of the processing-microstructure relationships in nanocrystalline intermetallic compounds, highlighting the potential applications of Al–Ni materials in high-temperature scenarios.
