Microstructural Characterization of Al2024/Red Mud MMC
In this paper the stir casting technique was used to fabricate Al 2024/red mud MMC. The MMC was developed
under the environment of Argon gas using controlled process parameters. The effect of different weight percentage and
particle sizes of red mud on the mechanical properties of Al/2024 MMC is reported. Scanning Electron Microscope (SEM)
images reveal the uniform distribution of the reinforced red mud particulates in the MMC. XRD examination confirms the
presence of red mud particles in the MMC. The results reveal that tensile strength and micro hardness of the Al2024/red mud
MMC increased with the increasing weight percentage and decreasing particle size of red mud in the MMC.
