Abstract
ABSTRACT The A7075 alloy metal matrix composites with various micro and nano particle reinforcements were enhanced matrix materials properties for applications in airbus, construction, automotive and marine industries. However, A7075 alloy metal matrix composites fabricated through molten-metallurgy route via stir-casting technique. Typically, micro and nanoparticle carbide, oxide, bromide, fibre and clay reinforcements effectively enhanced the microstructural observation, mechanical and several wear properties. The improved microstructural analysis like particle dispersion, interface bonding, particle size, generated precipitates, and elements was examined by SEM, EBSD, XRD, EDS SEM and AFM, microscopy. The mechanical behaviour of nanoparticle reinforced A7075 alloy matrix composites was superior as compared to micro reinforcements. Similarly, the tribological properties such as sliding, abrasive coarse and erosive wear behaviour were improved due to hybrid reinforcements into A7075 metal matrix composite; also this correlated with the obtained results and conclusions were drawn.
