Abstract

The process of mechanical alloying of aluminum alloy BAC1 with silicon carbide particles in a ball mill has been studied. An analysis of the stages of the process of mechanical alloying in the preparation of BAC1–SiC powder compositions was carried out and characteristic microstructures corresponding to each stage were identified. A hypothesis was formulated about the effect of collisions of granule particles on the formation of the structure of composite particles during mechanical alloying of an aluminum alloy BAC1 with silicon carbide SiC, which satisfactorily describes the experimental results obtained.
