- Abstract
The disposal of waste granite marble powder (GMP) causes environmental problems. The present work reports the impact of waste GMP as a reinforcement to produce composites. The Al-4032/GMP composites with 0%, 4%, 6%, and 8% (by weight) GMP have been fabricated through stir casting. A maximum 0.63% increase in theoretical density while a maximum 5.65% decrease in experimental density has been recorded for 8% reinforcement. The microstructure of the as-cast samples has been analyzed using an optical microscope, x-ray diffraction, and scanning electron microscope equipped with energy-dispersive x-ray spectroscopy. Other properties, such as ultimate tensile strength, micro-hardness, and impact strength of the composites, were enhanced from 69.4 MPa to 115 MPa, 131.4 HV to 174.1 HV, and 22.4 J to 32 J, respectively, because of the addition of GMP particles. Among all, the Al-4032/6%GMP composite appears to possess the best combination of all mechanical properties.
