This investigation aims to study the mechanical properties and microstructural analysis of aluminium matrix incorporated with different amount of Fe3O4 at (2, 4, 6, 8 and 10) wt.% with constant amount of Ni at 2wt.%. Al/ Fe3O4 +Ni hybrid nanocomposites specimens were prepared using powder metallurgy technique. Aluminium matrix nanocomposites (AMNCs) are considered as an important alloy due to their properties such as high strength, wear strength and light weight which enable them to use in many applications such as automotive, electronics and aerospace. There are many examinations have been carried out for the specimens of this work such as Field Emission Scanning Electro Microscope (FESEM) and X-Ray Diffraction (XRD) analysis to estimate the microstructure and phases of the prepared nanocomposites. Mechanical tests also carried out such as micro hardness test, compressive test and wear test to evaluate the mechanical properties of the hybrid nanocomposites. The results of this work show that Fe3O4 and Ni nanoparticles have been homogeneously dispersed in Al matrix by FESEM and XRD analysis. While the mechanical tests show that improving the compressive strength at 8wt.% by 55.36%, the highest micro hardness at 10% by 111.1% and also improving wear rate.
