Sustainable Development on Production and Characterization of Metal Matrix Composites using Stir Casting

Abstract In this study, four different combinations of aluminium metal matrix composites (AMCs) were produced using a computerized stir casting process. The feasibility car Scrap Aluminium Engine Head (SAEH) as material, Fresh Alumina Catalyst (FAC) and Spent (SAC) from petrochemical industries reinforcement material investigated. physical mechanical properties the cast samples tested through density, hardness, tensile, compression, impact test. Microstructural investigations carried out an optical microscope, scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), diffraction (XRD). Differential thermal analysis (DTA) Thermo gravimetric (TGA) also conducted to justify results obtained. indicated that SAEH reinforced with 5 wt% SAC exhibited lower porosity (2.6%) higher Brinell hardness (71.5 BHN), Vickers (307.1 VHN), tensile strength (217 MPa), compressive (426 MPa) than other composites. Additionally, composite showed highest (0.02375 J mm −2 ) DTA value (568.5 μ V mg −1 ). TGA result all had high stability, SAC-reinforced having stability (100.13%).
