Investigation on the mechanical, tribological, morphological and machinability behavior of stir-casted Al/SiC/Mo reinforced MMCs

Aluminum matrix composites (AMCs), reinforced with SiC and Mo, are formulated using stir casting. The influence of SiC and Mo inclusions on microstructural behavior, and machinability of composites was investigated. Microstructural behavior is analyzed using scanning electron microscopy (SEM), X-ray...
