An upsurging demand for high-performance, low-cost materials has prompted researchers throughout the world to shift their attention from monolithic to composite materials. A substantial effort has been made in this field to develop a wide range of metal matrix composites (MMCs). Because of their high corrosion and wear resistance, specific modulus, and weight for vehicle and aerospace applications, aluminium-based composites are regarded as the most favourable structural materials among MMCs. An extensive study on aluminium alloy 6063 (AA6063) is conducted. When reinforced with silicon carbide (SiC) and graphite (Gr), this metal matrix composite exhibits superior mechanical characteristics like improved strength, hardness, etc. A stir casting process is applied to fabricate the desired composites as it is relatively inexpensive and offers a wide selection of materials and processing conditions. Different analysis like X-ray diffraction, rockwell hardness test are conducted on the fabricated specimens. A comparative hardness analysis between the composites, AA6063/SiC and AA6063/Gr, results in superior hardness in the former by 3.18%. The X-ray diffraction indicates a uniform and non-contaminated casting and successful fabrication of the composite. The wire-electrical discharge machining (Wire-EDM) technique is used to assess the machinability of aluminium-based MMCs. Pulse-on-time, peak current and table feed are the three process variables used in an experimental design using a complete factorial to evaluate the effects on response measures of machining time, kerf width and material removal rate.
