Abstract
The aim of this study was to determine the compressive properties of silicon carbide (SiC) and zircon sand (ZrSiO4) particulate reinforced with ADC-12 alloy, ADC-12 alloy composite. In this experimental study, SiC and ZrSiO4 particulates reinforced with ADC-12 alloy composite were manufactured by stir casting methods. Compressive properties of these composite materials were investigated by different weight percentages of dual reinforcement combinations (9+3) %, (6+6) %, (3+9) %wt. silicon carbide (SiC) and zircon sand (ZrSiO4)respectively, The compressive tests were conducted to determine compressive strength and young’s modulus to investigate the effects of reinforce materials on different combinations of weight percentages. The outcome of the investigations reveals that the tensile strength of composites reinforced by Zircon sand (ZrSiO4) and silicon carbide particles with a total reinforcement 12% wt, and in this hybrid reinforcement the variations (9+3) %, (6+6) %, (3+9) % were taken in to account for investigating the properties such as density, compressivestrength and hardness of the composites synthesized by Stir casting technique, also compared between each other’s. The mechanical properties evaluation reveals variations in hardness and the compressive strength values with the composite combinations. From the experimental studies, the optimum volume fraction of hybrid reinforcement in ADC-12 alloy on the basis of microstructure and mechanical properties it is found that the (6+6) wt.% combination.

Summary
Aluminum alloy matrix composites (MMCs) have emerged as a good quality of materials capable for advanced structural, automotive, electronic, thermal management, and wear applications. ISSN: 2454-1907 performance of metal-matrix composites is superior in terms of improved physical, mechanical, and thermal properties (specific strength and modulus, elevated temperature stability, thermal conductivity, and controlled coefficient of thermal expansion). The performance advantages of metal matrix composites are their tailored mechanical, physical, and thermal properties that include low density, high specific strength, high specific modulus, high thermal conductivity, and good fatigue response, control of thermal expansion, and high abrasion and wear resistance. Low wear resistance of aluminum has caused reducing its tribological uses; the aluminum matrix composites reinforced with ceramic particulates have shown significant improvements [2,3,4,5,6,7,8,9]. The effects ofZrSiO4 and SiC reinforcing particles on microstructure and mechanical properties of this alloy have been investigated and compared
