This study examines the production and analysis of aluminum matrix composites reinforced with Fe-based metallic glass (FMG) using powder metallurgy techniques. FMG particles with nominal composition Fe75Si15B5Zr5 were synthesized using the mechanical alloying process. For the fabrication of composites, two methods were used: (a) mixing gas atomized pure aluminum (GA) powder with FMG powder and consolidating via spark plasma sintering (SPS) to form the GA/FMG composite, and (b) ball milling the GA powder before mixing with FMG powder and SPS consolidation to produce the (GA+BM)/FMG composite. As a control, pure aluminum powders before and after the ball milling process were also consolidated using SPS under identical conditions, which were designated as GA and GA+BM, respectively. Results showed a notable difference in relative density (approximately 5%) between the (GA+BM)/FMG and GA/FMG composites. Quantitative analysis revealed that reinforcing particles were more evenly distributed in the GA/FMG composite. The (GA+BM)/FMG composite exhibited a compressive yield strength of 156 MPa, double that of the GA/FMG composite, but with reduced ductility. Fractography indicated that the (GA+BM)/FMG composite was more brittle than its GA/FMG counterpart.
