In-Depth Examination of the Mechanical Properties of AA6061/MoS2/SiC Hybrid Composites

In the contemporary context, composites have emerged as a prominent alternative to ferrous alloys. Among these, aluminium stands out as a superior substitute, primarily owing to its lightweight nature, high strength, low density and corrosion resistance. A notable advancement involves the amalgamation of non-ceramic reinforcements such as SiC, B4C, Al2O3 and TiB2 with non-metals like MoS2, resulting in the formation of hybrid metal matrix composites. This study focuses on the examination of AA6061 material through the stir casting process. In this procedure, varying percentages (2, 4, 6%) of SiC, along with a constant 0.5% of MoS2, are added to the matrix material. Subsequent to this alloying, the tensile test, hardness assessment and impact test were conducted for all three prepared materials. The results indicate a direct correlation between the increase in the wt.% of SiC and the rise in tensile and hardness value. Notably, the AA6061 + 6% SiC + 0.5% MoS2 composite exhibits the highest performance among the tested materials.
