Abstract:

Advanced composite materials, specifically the Al/SiC metal matrix composite, have become increasingly important in the aerospace and automotive industries due to their superior properties. In this study, various weight fractions of silicon carbide (SiC) were utilized to examine the mechanical properties of metal-matrix composites made of aluminum (Al-6063) and SiC. Stir casting was utilized in an air environment to create these (Al-6063)/SiC reinforced particle MMCs, with different reinforced particles added in weight fractions ranging from 2% to 10%. The SiC reinforced particles varied in size from 25 to 40 microns. Microstructure investigation revealed that particle distribution improved as the weight fraction of SiC increased. Mechanical parameters including ultimate tensile strength (MPa), percent elongation, hardness (HRB), and yield strength (Nm) were evaluated for the prepared specimens of MMCs. Results showed a gradual increase in composite hardness between 2-6% and a significant increase between 8-10%. With an increase in the weight fraction of reinforcement, tensile strength and ultimate break load also improved by 15.8 to 27% and 2-15%, respectively.
