N2 - In the present study, a vacuum-assisted stir-casting process was made to synthesize nano-molybdenum trioxide-strengthened magnesium alloy composites of varying weight proportions. Morphological analysis was used to study the uniform distribution of ceramic reinforcing particles in the synthesized magnesium nanocomposites. ASTM standards were used to examine the mechanical properties of the intermixture. It was observed that the nano-MoO3 ceramics were uniformly distributed within the matrix alloy, no residual porosity was observed, and the grain size of the intermixture was observed as 59.82 +/0.001nm and due to enhanced grain refinement and interfacial reaction between the intermixtures, the mechanical properties of nanocomposites, such as tensile, compression, flexural and impact strengths, significantly increased over the as-cast magnesium alloy. The corrosion resistance was improved due to the reduced size of the Mg17Al12 phase and the more uniform dissemination of ceramic strengthening particulates. Further, the improved load-bearing capacity and transfer layer enriched the wear resistance of magnesium alloy nanocomposites for all weight proportions.
