Investigation of mechanical behavior of Al 6063 & SiC composite materials

The purpose of this work is to focus about involved in designing metal matrix composite material is to combine the desirable attributes of metal and ceramics. The microstructures, mechanical properties of silicon carbide (SiC) reinforced aluminum 6063 (Al 6063) matrix composites (AMCs). AMCs of varying SiC content (5 wt. %) were prepared by stir casting process. Microstructures, Rockwell hardness test, tensile strength and Impact (Izod) Test performance of the prepared composites were analyzed. AMCs materials than unreinforced materials such as greater strength and high specific modulus, improved stiffness. Aluminium was used as a base material where SiC used for reinforcement material. SiC particle is preheated at 80 °C for three hours. For mixing of material we are used electric furnace attached with graphite stirrer which is used for uniformly distribution of material. During mixing of SiC. it was stirred for 10 minutes at 100 rpm. The melt convert into solid in the mould. The results found that SiC in Al 6063 increased hardness and tensile strength and 5 wt. % SiC reinforced AMC showed maximum hardness and tensile strength. The scanning electron microscopy (SEM) test was done to know the distribution of SiC and aluminium particles in aluminium alloy, where energy dispersive X-Ray (EDX) tests was performed to know the presence of the phase of reinforced material and it was found that the composite had better properties than pure aluminium.
