Aluminum alloys, A-7075 metal matrix, Stir casting route, Agricultural waste composites, Rice Husk Ash, Ageing Studies


There has been an increasing interest in composites containing low density and low-cost reinforcements. Composites find a major usage in society with the advancement of the technology and research. A7075 is an Aluminum alloy series which is the strongest alloy of the aluminum present anywhere. This makes it find its usage in aerospace (making of space ship hulls) and defense sectors (M-16 rifles etc).This research paper is aimed to increase the properties of the alloy further by adding a reinforcement which is agriculture based and is abundantly available. The alloy ingot was cast and tested for basic mechanical properties, compressive strength and also for the strain hardening rate after the heat treatment properties. The composite was cast using stir casting technique. The composite formed was A-7075 with 5% RHA (RICE HUSK ASH). The reinforcement (preheat treatment), composite and the base alloy was subjected to T6 heat treatment condition and then tested for further mechanical properties.
