Abstract
The present study investigates aluminium alloy powder (Al7075) of mesh size 60 μm and the reinforcement SiC of varying its weight percentage (2 wt%, 4 wt%, 6 wt%) and keeping constant Al2O3 (2 wt%) of particle size <50 nm has been used to synthesis aluminium alloy hybrid nanocomposites. The compaction pressure (350 MPa) and the sintering temperature (750 °C) are used to develop such hybrid composites. The microstructure and mechanical behaviour of progressed composites have been characterized as per ASTM standards. The aluminium alloy hybrid composites sintered effectively and the strengthening particles are consistently disseminated in the matrix alloy without indication of the cluster along with the fine grains of intra dendrite grain boundaries that are precipitated throughout grains of an aluminum matrix. In comparison with base alloy, the hardness (14%) and compressive strength (24%) of synthesized composites have been increased invariably. ASTM B117 salt spray experiment has been performed to study the corrosion properties of incorporated composites. It has been inferred that corrosion-resistant is improved due to the presence of interface AlC2, Al2SiC between the intermixtures. This act as a barrier for disruption and it minimizes the effect of oxidation of developed aluminium hybrid composites.
