Fabrication of Aluminium 6082–B4C–Aloe Vera Metal Matrix Composite with Ultrasonic Machine Using Mechanical Stirrer

The given research deals with the study of metal matrix composite in which aluminium 6082 series was selected as the matrix and boron carbide (B4C) along with aloe vera powder were selected as reinforcement with different weight percentages. The use of aloe vera powder helps in making a green metal matrix composite as it is organic material and biodegradable product. For the fabrication of MMC with 4% or 8% of B4C and 8% or 4% aloe vera powder, a furnace with ultrasonicator and mechanical stirrer was used. The casting was carried at 900 °C to melt the aluminium for about an hour along with the reinforcement, and then the stirrer was rotated to mix the reinforcement properly. The spectroscopy test was carried to get the different contents of the B4C and aloe vera powder. The reinforcements were distributed homogenously, found by the optical micrographs.
