Microstructure and some mechanical properties of fly ash particulate reinforced AA6061 aluminum alloy composites prepared by compocasting
Graphical abstract . Display Omitted Highlights ► Fabrication of AA6061/fly ash AMC by compocasting method. ► Incorporation of fly ash particles into the semi solid aluminum melt. ► No interfacial reaction between the aluminum matrix and fly ash particle. ► Uniform distribution of fly ash particles having clear interface and good bonding. ► Fly ash particles enhanced the mechanical properties of the AMC.
Abstract Fly ash has gathered widespread attention as a potential reinforcement for aluminum matrix composites (AMCs) to enhance the properties and reduce the cost of production. Aluminum alloy AA6061 reinforced with various amounts (0, 4, 8 and 12wt.%) of fly ash particles were prepared by compocasting method. Fly ash particles were incorporated into the semi solid aluminum melt. X-ray diffraction patterns of the prepared AMCs revealed the presence of fly ash particles without the formation of any other intermetallic compounds. The microstructures of the AMCs were analyzed using scanning electron microscopy. The AMCs were characterized with the homogeneous dispersion of fly ash particles having clear interface and good bonding to the aluminum matrix. The incorporation of fly ash particles improved the microhardness and ultimate tensile strength (UTS) of the AMCs.
