Mechanical alloying is a widely used alternative to the liquid-phase method of embedding reinforcements to manufacturemetal matrix composites (MMC). In this research, high-energy ball milling was used to distribute various volume fractionsof sub-micron-sized SiCpparticles (2, 10, and 20 vol%) in AA2024 aluminum powder alloy, focusing on powder morphologyand milling conditions. An increase in the full width at half-maximum and the shifting of peaks at higher angles wereobserved after mechanical alloying. These examinations were attributed to changes in the lattice parameters of the matrixalloy. It was noted that the temperature and loading pressure during the die compaction stages of MMC powders directlyaffect the compact density, whereas the volume fraction of SiCpchanges hardness. Compression testing, conducted at elevatedtemperatures to evaluate the plastic properties of the material, showed sufficient ductility characteristics for thermomechanicalprocessing.
