Influence of microstructure in mechanical properties of light weight/high strength Al-7075 reinforced with nano and micro ZrO2 alloy metal matrix composites

Applications in engineering have made extensive use of aluminum 7075 alloys and the metal matrix composites they produce. Under the present circumstances nano-micro ZrO 2 fiber reinforced aluminum metal matrix composites, i.e. eventually, ceramic particle reinforced aluminum metal matrix composites may be replaced by nano-micro ZrO 2 . In order to improve microstructural qualities and mechanical strength, the right weight percentage of nano-micro ZrO 2 is added as reinforcement when creating metal matrix composites using the stir casting technique. Through microstructural analysis using optical and scanning electron microscopy, we saw where the Nano(N) and Micro(M) ZrO 2 were and how they interacted with the scaffold. Due to the inclusion of reinforcement made of ZrO 2 , intermetallic connections between aluminum and ZrO 2 are revealed by X-ray diffraction analysis. The research results show that adding 5% M- ZrO 2 steel whiskers to the composites improves their properties, including their hardness and tensile strength. The mechanical properties are better understood as a result of this study, since the aluminum 7075 alloy has almost three times the tensile strength of the 5% M-ZrO 2 . These results highlight how material performance can be improved for a wide range of engineering uses.
