Production and Characterization of Aluminium Metal Matrix Composite Reinforced with Al₃Ni by Stir and Squeeze Casting

Abstract:

In the present work AA1100/ Al₃Ni MMC was successfully fabricated using the in-situ method of stirring and squeeze casting. The effects of amount of Ni powder on the formation and mechanical behavior of Al-Al₃Ni MMC were investigated. The fabricated MMC was characterized using XRD and optical microscope. The XRD patterns clearly indicated the presence of Al₃Ni particles without the formation of intermediate phases. The in-situ formed Al₃Ni particles were found to have uniform distribution, good bonding and clear interface. The mechanical and tribological properties such as hardness, Ultimate Tensile Strength (UTS) and dry sliding wear behavior of AA1100/ Al₃Ni MMC were compared for stir and squeeze casted MMCs with different percentage in weight of Al₃Ni (5, 10 wt. %) and it was found that properties improved with increase in Al₃Ni content and all properties of squeeze casted MMCs were superior to stir casted MMCs.
