Mechanical Behaviour of Silicon Carbide-Fly Ash Hybrid Aluminium Alloy Composites Subjected to Age Hardening
Main Article Content
Abstract
Identification of age hardening behaviour for silicon carbide (SiC) and fly ash reinforced metal matrix composites (MMC) is required for aluminium based automobile components. The project deals with the fabrication of Aluminium Alloy 6061 metal matrix composite and characterize their mechanical properties such as hardness and tensile strength. In the present study a modest attempt has been made to test aluminium based silicon carbide and fly ash particulate MMC Age hardening behaviour of this MMC that was developed from blending, through powder metallurgy process is analysed. T6 heat treatment on AA6061/7.5% wt.of fly ash/15% wt. of silicon carbide made 20% increase in the hardness and by 18% increase in the ultimate tensile strength while 4% of ductility reduced.
