Microstructural analysis, micro hardness and tensile strength of silicon carbide and zirconium silicate dual reinforced particle ADC-12 alloy composite

The aim of this study is to determine the tensile properties of silicon carbide (SiC) and zirconium silicate (ZrSiO₄) particulate reinforced with ADC-12 alloy composite. In this experimental study, SiC and ZrSiO₄ particulates reinforced with ADC-12 composite were manufactured by stir casting methods. Tensile properties of these composite materials were investigated by different weight percentages, 3%, 6%, 9%wt silicon carbide (SiC) and 9%, 6%, 3% wt of zirconium silicate (ZrSiO₄) respectively. The tensile tests were conducted to determine tensile strength and young's modulus to investigate the effects of reinforce materials on weight percentages. The outcome of the investigations reveals that the tensile strength composites reinforced by Zirconium silicate (ZrSiO₄) and silicon carbide particles with a total reinforcement in Wt% is 12, 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, tensile strength and hardness of the composites synthesized by Stir casting technique. The mechanical properties evaluation reveals variations in hardness and the tensile 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.
