OPTIMIZATION AND BEHAVIOR OF NANO SCALED SILICON CARBIDE REINFORCED MAGNESIUM COMPOSITES DEVELOPED USING POWDER METALLURGY TECHNIQUE

In this research, a magnesium alloy was developed by powder metallurgy technique and optimized using Taguchi based Grey-Analysis method. A varieties of weight fractions of SiC is being reinforced with the optimized compositions of magnesium alloy. Simultaneously the impact over the mechanical properties after the addition of SiC with the different strain rates have been studied. Mg-Zn-CuMn alloy was optimized by varying the weight fractions of alloying elements using Taguchi based grey method. The optimal compositions of Mg-3Zn-1Cu0.7Mn (ZC31) Mg alloy was obtained. ZC31/SiC composite was formed by powder metallurgy technique and then hot extrusion was performed and thereafter the mechanical properties were studied using 0.005s-1, 0.016s-1, and 0.05s-1 strain rates.
